By "Menu Bar" I mean the strip up top with the Menu and compass. I'm not conversant in Flash, but from what I've seen this should be doable.
Essentially, at 1680x1050, that is a lot of wasted blank space. My imagining is simply moving some of the more used items from the Menu into that space, similar to this (quick hack job)
The compass can be moved (I dunno why it isn't attached to the map by default) and more entries added, or the entries can be reduced down to their icons, or even something more dynamic like having the icons and have their text expand when you mouseover.
Whatever, I'm sure you get the idea. That bar, judging from previous games with UI mods, will probably be used for lots of things (number of items in inventory, amount of credits and tokens, etc etc)
