Is there a "Places" menu for Ubuntu Unity?

Question

I'd like to know if it's possible to put a "Places" tab in the upper menu of Ubuntu, such as CentOS, Debian, etc.

Thanks

Answer 1

I tried several existing ones, but could not find a working Places indicator. The ones I found were outdated, ppa's were no longer maintained.

Modular Places menu

So, below a freshly written one: Places & Files indicator for Ubuntu.

The ppa version is a modular one; you can choose what to show in the menu:

[]

In the full version:

...or the smallest, only showing recently used:

Installing from ppa

sudo add-apt-repository ppa:vlijm/placesfiles
sudo apt-get update
sudo apt-get install placesfiles

A simplified version to show a places menu, bookmarks and recently used files

How to use (if not installed from ppa)

1. Copy the script into an empty file, save it as places_indicator.py

2. Save the icon (right-click > save as) exactly named:

   dir_icon.png
   

   

   ..in one and the same directory as the script.

3. Test- run the script by the command:

   python3 /path/to/places_indicator.py
   

4. If all works fine, add it to Startup Applications: Dash > Startup Applications > Add. Add the command:

   /bin/bash -c "sleep 10 && python3 /path/to/places_indicator.py
   

About the indicator

The indicator shows:

1. The home directory
2. All directories (local bookmarks and smb) in
   • ~/.config/gtk-3.0/bookmarks
   • ~/.config/user-dirs.dirs
3. Network
4. Connect to network
5. Computer
6. Recently used files (lats 10 as it is, could be easily changed)

Changing/added/removed bookmarks are updated dynamically

Answer 2

Update Feb/24/2017: the indicator now has option for pinning web links

Introduction

NOTE: The previous version of this answer can be found under the edit history, althought it is no longer relevant.

The indicator presented below has been intended for a different question, but since opportunity presented itself, I've decided to release it here. The Files Indicator is simple indicator for accessing user's files and folders. It allows checking recently used files, bookmarking files and directories. In particular, the Places menu is specifically relevant to this question.

As you can see from the screenshot, the indicator also supports locales other than English, so if your system uses something other than English, it will work.

Update: indicator now also supports launching .desktop files that have been pinned. For instance if you have firefox.desktop pinned, it will launch firefox. Thus, the indicator can be used as quick launcher for programs. The feature is on the way into PPA at the time of writing (Nov 19, 7:53 pm GMT, should take about 24 hours to process), but is already on github as well as here, in updated source code.

Obtaining the indicator

The indicator is available from my personal PPA as well as GitHub. Use the following steps to obtain it:

sudo add-apt-repository ppa:1047481448-2/sergkolo
sudo apt-get update
sudo apt-get install files-indicator

Configurations

The indicator is configured via two json files stored in user's home directory.

~/.files_indicator.json controls user interface , the length of menu entries and maximum numbers in the Recent Files Menu.

{
    "name_length": 30,
    "max_items": 10
}

The ~/.pinned_files.json controls the lists of pinned files and folders. Each item is a list/array.

{
    "dirs": [
        "/home/xieerqi/\u56fe\u7247/Wallpapers"
    ],
    "files": [
        "/home/xieerqi/work_in_progress/videonauth_code.py",
        "/home/xieerqi/work_in_progress/spin_button.py"
    ]
}

Answer 3

Okay guys what I did was just installing Ubuntu-Gnome and enable the 'Places' extension in Tweak tool and got it. Gotta say Ubuntu Gnome looks much more better than Unity
