Thought I'd add my opinions on your suggestions:
1: This sounds useful.
2: I don't really see the point as there is only one ribbon that's
exclusively for a specific screen.
3: Have you tried the "Snap to grid" feature in the ribbon? (I prefer an 8x8 grid)
2 - I really don?t use the Event ribbon, but I tought it would be useful ;]
3 - Thanks, I?ll try to align that way ;]
