I haven't had to use any application like that in a while, though I'm sure you're right that they exist. Could you give me an example of an application feature that's only accessible from the system tray?
What do you find not great about mouse/keyboard GNOME? All the gestures I know have pretty simple mouse and keyboard equivalents. So far I just gesture three fingers up/down/left/right, which I can do on a keyboard with super/alt-super-left/alt-super-right or on a mouse with hot-corner/corner-click/corner-scroll. If there's a gesture I'm missing out on please let me know, I always like to learn new tricks.
