Ive just released a new Flash MX 2004 Command; Delete Empty Keyframes, that helps me when i am modifying flash files that have been developed by somebody else. This command along with another that i will be releasing shortly; Delete Empty Layers/Folders makes any flash movie alot tidier, by removing any redundant keyframes that have been put there by a designer or developer and never used. A tidy/organised flash movie is easier to work with. This Command knows the difference between a redundant keyframe and a keyframe that is a label/comment, or just there to hold some actionscript, or a keyframe that contains a sound or a keyframe that is there to stop displaying something from the previous keyframe.
