Note: I do not maintain this code. This is a much better plugin: https://github.com/phocean/TopIcons-plus
Shows legacy tray icons of Gnome shell on top panel. Tested with Gnome 3.14.
Fork of http://94.247.144.115/repo/topicons/. Topicons didn't have an option to set icon size, so I added it.
This is just a try, without any warranty.
$ git clone [email protected]:mjnaderi/TopTray.git
$ cd TopTray
$ makeYou may need to restart the shell (Alt + F2 then r), and enable extension using Gnome Tweak Tool.
Reduce space between icons (Or add an option for it)
