About the menu closing: I think the behavior comes from an older design. On older OS versions (I don't know if this changed with OS X or if it was earlier) you had to hold down the mouse button the whole time you traversed the menu. Letting go of the mouse button over anything but a menu item resulted in closing the menu. You can still do it this way. And now, even though the menus are 'sticky', they close when you click on anything that isn't a menu item. I'm so used to this behavior now that I use it to close menus. Still though, it would be interesting to try it both ways for a while.
