Flash 4 had a very nice interface full of palettes. Flash 5 dropped them all in favor of a "smart" inspector that never showed me what I wanted to see without a couple of extra clicks and a half-second wait. This was about half of why I dropped out of the animation industry, it was a complete flow-killer.

This happened because Adobe sued Macromedia over palettes.

Annoyingly enough, the interface has not substantially changed in the intervening years despite Adobe eating MM.
