workspaces corrupt preferences
Nearly every time I encounter a bug, it's due to work spaces. It's the single most corruptible aspect of AE. The default spaces are terrible. Worse, I go though time and effort to tweak my setup and ultimately have to blow away prefs when something like ram preview or playback becomes broken, due to corrupt preferences.
furthermore... the amount of preferences stored in the same place is silly. why do we have to loose and rebuild so many options each time we reset them. do what resolve does, split them up into different groups.
