I’m always looking for a nice debugger to use on the fly, the “De MonsterDebugger” looks really nice.

De MonsterDebugger is an open source debugger for Adobe Flash, Flex and AIR. De MonsterDebugger is made in Flex and AIR by design studio De Monsters.

One of the nicest features in my opinion is the live editing of properties, very handy when fiddling to position elements correctly.
