If I have 3 windows opened in the same application (e.g Google Chrome) I get this in the Unity Bar:

3 open windows in Google Chrome

OK, that's good and expected. If I click that, it will Scale the windows that belong to that application, like this:

3 scaled open windows in Google Chrome

Great! That's what I want to achieve more often by using hot corners. I did that with TopLeft and Scale All Windows, like this:

All scaled windows

How can I achieve the scale of only the application windows (like Chrome) with a hot corner (like TopRight)? I've already tried "Initiate Window Picker for Window Group" but it doesn't work.

Am I missing something? Using Ubuntu 12.04 and the Scale / Scale Addons plugins.

That's a bug 774059 on Launchpad.

This is the "answer" (it should be possible, but it isn't because of a bug). Let's all hope someone fixes that. – AeroCross Oct 12 '12 at 22:14

If you want the scale plugin to only scale Chrome windows you will have to open CCSM which I assume you have installed already. Then go to the scale plug in. Click on the Behaviour tab then where it has "Scale Windows" and a bunch of types you will have to clear that field and then enter:


In that field. Then the scale plugin will only effect Google Chrome windows, However you will lose the ability to scale all other windows using your hot corner/keystroke. If you don't like the changes you can hit the X button on the far right side by the "Scale Windows" dialogue box.

Yup, already installed CCSM. The thing is that, as I stated, I need both hot corners (all applications and application windows). Using class=Google-chrome would wreck that. It's worth noticing that I want the functionality for all the application windows, not some specified. Google Chrome was just an example. – AeroCross Oct 11 '12 at 21:18
AH okay I understand what you are saying. I don't think that is possible with Compiz, unless you somehow had multiple copies of the scale plug-in. I was thinking if there was a Window match type for open or active/focusses windows, you could set it to active and similar, but according to the Compiz Wiki there is not. – Weylin Schreck Oct 11 '12 at 21:28
