I'd love the ability to undock panels (states, properties,
etc) and drop them on a second monitor, like in CS3. The interface
feels crammed together right now, and building an app for a
resolution greater than 800x600 is difficult. Scrolling
horizontally is no fun, and a constant frustration.
There's an Eclipse bug logged for this issue:
views doesnt work on OSX.. Looks like it's already fixed. I
just tried in Eclipse 3.3RC3 build (with and without Flex Builder
Plugin) and it seems to work fine.
