Tixati v2.31 is not reachable from top MenuBar(Tixati's tray option) in Ubuntu 15.10 Unity. There should be a small Tixati icon on MenuBar.
While choosing "Minimize to tray/run in Background" option at the exit, Tixati works fine but it is not shown in MenuBar.
This problem was present in previous versions also.
Tixati works well with Gnome 3 but not with Unity 7 interface.

Yeah, mine too on ubuntu 14.10lts, I know it's a bug but I kind uf just got used to going to the launcher. Moot point as I'm about to leave ubuntu anyway...
