Hiding an application from switcher (alt+tab)
Solution 1:
I solved it after finding a small thread on Ubuntu forums. I think this solution can be applied to any program
Install compizconfig-settings-manager:
sudo apt-get install compizconfig-settings-manager
Go into Window Managment
and Window Rules
, there add:
Skip taskbar: title=Cairo-Dock
Skip pager: title=Cairo-Dock
and finally go back to the main settings and enable the Window Rules
by checking the box
It is also possible to change the switcher by activating the ring or shift switcher and replacing the Unity shortcut with the custom switcher. In their respective menus you can choose what kind of windows it should display.
