We’'ve been trying buzz for a while now, it has potential.
My biggest use case is when someone isn’‘t paying attention to spark/can’‘t see the window and so they’'re not seeing my message. I have to yell across the room to get their attention, not very nice!
I think buzz in windows should flash the task bar button to show notification and also, activate the tab of the person who buzzed you as the current tab. Currently you need to switch back to the window and then search the tabs looking for the BUZZ word to see who did it.
With regards to the button, i can see the issue with it being next to all those others where it might be accidentally pressed but you don’‘t wanna move it somewhere odd… perhaps aligning just that button to the right of the window would be a better idea. So it goes (Left hand side: Smiley’'s, Spell Checker) (Right Hand Side: Buzz button).
It’‘s a useful feature, no doubt… i just dont think it’'s being implemented correctly yet.
