I agree with what has been said so far and would like to echo that I would like to be able to use
deep, rich colours, not just on the side edge (in Track View) or bottom edge (in Console View). I'm not a pastel or greyish grey fan. Sorry to nag, but I wish for this every time I open Sonar.
After all, people vary. Some likely prefer a quiet, non-intrusive (engineer-serious-business-this-is-not-a-toy) atmosphere so that they are not distracted visually and can concentrate on the task at hand.
Others long for the freedom and tools to make their visual environment as creative and inspiring as possible, even if others find their taste in colour combinations questionable. :)
The great news is: Giving the second group what they want won't deprive the first group of a single thing. Everyone can work in the environment that satisfies him or her.
Thanks for listening.
