My CLion version is 2016.1.2
Gnome proposes a vertical bar (the dash) with a list of favorite applications.
The usual way to add favorites to that bar is
1 - launch the app
2 - The application's icon appears in the Dash (the dash shows all running application additionally to the favorites)
3- right click on the icon and select 'add to favorites'
But for an unknown reason, it does not work for CLion. The CLion icon appears but the choice "add to favorites" is not present in the menu.
It works well for any other applications . (For instance pyCharm)
