It would be great to have a Pre-Comp DropDown window so that we dont need to move out of the original window to edit elements. We could have a scrub window to look through pre-comp and isolate effects and parameters. As there are so many twirl down menus , it would not matter if there a few more. Even if there was a little scrub window or something outside pre-comp to enable/disable layers etc. Any little thing would make life with pre-comps a lot easier
