I recently shifted from Cinnamon to GNOME 3. So far so good. But I found that my app which has an icon in Panel, does not do so. I added KStatusIcon extension from Extensions website but it renders my icon invisible (if I drag cursor over it, I can see my app name pop up, but icon is not there). I think this is due to the issue that my app is powered by Gtk and not my Qt.
So my question is, why is an AppIndicator not supported? It is really useful, like a messenger could show how many unread messages are there and so. GtkStatusIcon also seems to be good but it is depreciated and no alternative is mentioned in the Docs.
Got any idea?
