fix the Layers palette; modernize it.
The layers Palette in Illustrator Predates most Design apps out there. Because of that, many of its behaviors are critically out dated and in great need of a top - bottom update.
some critical things to fix:
1. Selection tracking should be unified. Selecting in the Layers palette should ALSO select the elements in the document. Throw away the confusing 2nd step there.
naming. make it more flexible. IE: add built in options for the renaming that occurs when you copy a Layer. Add the ability to rename selected layers with one text entry. Add to that, a simple Scripting system that allows a search and replace, append/prepend command. You could invoke that when multiple layers are selected and then double clicked in the layer palette.
stop blocking the user from performing actions on layers that are hidden. We're not stupid, and YES, we want to do that.
