From the "are you with me?" series:
It's great that I can define my own coding style. It's great that I can define my own coloring scheme. But how about providing more ready-to-use coding styles and coloring schemes, out of the box?
This is specially important for coding styles, since there are just 3 or 4 common used styles around, and providing them out of the box would save many users the pain to go thru the (extensive) coding style panel.
For color schemes, I think JetBrains should provide at least a dark background alternative to the default scheme, out of the box (shameless plug: The "Dessert" scheme, currently found on the Wiki is a good one).
