Those are nice! I like those icons!
These colour themes just get better and better. Just when I think I've found my favourite, someone else comes along with something equally interesting, if not more so.
The fact that we can switch between the various themes depending on mood and eye strain, etc. is just great.
Sometimes the muted blue themes are nice when you are tracking, but then there's another recent one that uses dark colours and bright greens a la Ozone that is nicer for editing sessions, because of the clarity, etc. . . .
It all really adds to the usability of RPR. I'm more inspired to want to create, etc. with RPR because of this stuff.
