For example, I ran Firefox and opened Askubuntu. Then opened some link in a new window. As a result, I have two windows of Firefox and one icon of Firefox on the launcher. I want to have an icon for each opened window.
How do I do?
The reason why this feature is not available is because of a productive (and actually not counter-productive) reason. Please give me a second to explain so you can also understand. Follow me on this one for the reasons behind this:
Imagine you need to open not 2 Firefox Windows, or 4, but 10 or 20. Now imagine having the Unity Launcher with the common icons it has plus 10 to 20 firefox icons there. You would see 10-20 firefox icons, all the same, and would first have to guess which one takes you to the webpage you wanted to go. Secondly, if you wanted to close them you would have to go, one by one and start closing them manually.
So we have 3 issues:
With this 3 issues an idea came to mind. Group them together in a single icon in the Launcher that represents the application in use and offer in a one right click solution, all the options needed to cover the rest of the issues.
Between 12.04 and the soon to be release 13.04, there has been much work put out to not only solve this 3 issues, but to help the end user work faster and easily, with just a minor learning curve. The end result (For 13.04 for example) is an icon that can deliver many windows of the same application and offers the possibility to change between them in an almost one click solution.
Some of this images can show you an example:
In this example, I have Nautilus opened 4 times, one Nautilus is left opened on a folder called Docs. Another is opened pointing to HOME. Yet another is opened showing the Documents folder. One last Nautilus window is opened on a movie I have. By right clicking on the Nautilus icon I can easily switch between them by simply clicking on them. The window will maximize and gain focus, leaving me with a Window I can start working immediately.
Here you can see the same example. Many Chrome Windows opened. Each with several tabs and each one showing the exact webpage where I left them:
Lastly, your example, Firefox. Here you can see several Firefox Windows opened. And each Window is shown when I right click on the Firefox launcher icon:
Not only can I manage several windows of the same app quickly, but if the need arises, I can close them all with the "Quit" option in the launcher icon's context menu. Saving me time in case I had 20 Firefox Windows opened.
I also felt the pain when I could not access my multiple windows in an easier manner, but after using this method, I found it was easier, quicker to search in, since I did not have to go through many launcher icons to guess which one is the one I was looking for, neither did I have to scroll down the Unity launcher between 20 Firefox Windows, 30 Chrome ones and 40 Nautilus ones just to get to the one I needed. Overall, it saved me time when I needed to find the correct one and work on it.
As you can see, it focused itself to be more productive to the end user, with just a slight touch in the learning curve.
Now, if you actually wanted to have the option to ungroup them, it would involve, downloading the Unity source and any dependencies related to it. Modifying the code so you could actually ungroup them, by default or as an option, compile this and install it on the system, making your Unity be able to ungroup them as you wish. But in this case, I would ask, is it better than the solution provided by the Unity Development Team?.
This of course is left to each person to decide on how they like to use their system. In my humble and honest opinion, I feel the change made by the Unity team, solves several issues I had on 11.10 or even on 12.04 related to this, and the way it works on 13.04 is much better than I anticipated.
I am sorry there is no straight and specially, easy answer and I really hope you can take a moment and test out the behavior of this feature as it is on the latest Ubuntu version (Specially 13.04 if you have the time).
This is by no means a solution to what is asked but may be helpful
Research shows there are a lot of people asking and wanting this feature that is being asked about. There is bound to be a working solution. Searching related questions here on Ask Ubuntu gives reference to gnome environment or others which may give useful building blocks for working it out for Unity. May be time to accept there is not an easy solution for ungrouping windows in Unity launcher icon.
"Alt and `" (Button above Tab) switches windows of app as does "Super and w" All credit to Jo-Erland Skinstad who answered this Ask Ubuntu question. Depending on the mouse (if any)being used any keyboard shortcuts can be easily mapped to one button whether it be on mouse or keyboard which would give one click to show open windows and then one more left click to select which would make window switching slightly easier. To remap keys look here or xboxdrv would be another option- "It is also possible for xboxdrv to read input data directly from an event device, this allows the use of the configurability of xboxdrv on regular PC joysticks, keyboards and mice and thus lets xboxdrv serve a similar purpose as joy2key. See the option --evdev below for more information." as long as hotkey is not part of shortcut. Sure is doable with a little research.
Additionally an Ubuntu Forums user has filed a request for what you ask using Brainstorm. Other Ask Ubuntu questions mentioning editing or making quicklist menu/icon for application may be possible for an advanced user but can only find working examples for gnome environment and not unity like shown here and they do not use Firefox as a working example. The Ubuntu Forums question that is referred to can be found here and the Brainstorm request/idea can be found here So go get voting!
Turning my comment into an answer:
However it is not very stable (some window icons disappear after changing settings or relaunching and some of the launchers icons gets doubled when relaunching). Also it is not matching some windows correctly, such as eclipse and thus leaves a launcher icon at the same time as adding a task icon. Same for shortcuts to Virtual Box VMs.
If anyone knows a better alternative or if someone can tell me if patching unity for this would be a huge work or not, I would be glad to know ;)
If you want a taskbar you could try tint2. works great for me.
Tint2 Website : http://code.google.com/p/tint2/
From Webupd8 : Tint2 is a lightweight panel/taskbar intentionally made for Openbox3, but should also work with other window managers such as Gnome.
You can install tint2 by issuing the command
If you'd like to customize the position and the look and feel, there's an article on WebUpd8 with a GUI customizing tool here : http://www.webupd8.org/2009/09/how-to-install-and-configure-tint2.html
If you need a taskbar icon/item per opened window, then solution could be to use gnome classic or Xubuntu components, not unity. For example Xubuntu (Xfce) works pretty well this way. Solution for you would be to install Xfce and start Xfce session instead of unity session.
On the other hand you will lost a lot of unity functionalities via alt and master keys, lot of keyboard shortcuts, etc.
Additionally, if you follow this question: How can i install XFCE along side unity? , you will find how to install xfce and additionally, there should not be any conflict between unity and xfce, so you can configure a new xfce vertical panel (just tested on Xubuntu) which contain just icons not names of the opened windows ad place it to the right corner for example.
It is not exactly what you need, but I think Ubuntu launcher does not support such functionality - this is a real life.
I don't know if that's possible. However, each additional window of an application will add a new tick to the left side of that application's icon in the launcher (up to three ticks I believe).
Clicking the icon will bring up a screen of all the open application windows for you to select which one you want.
