1. Thnx for the appreciation about Tron Punk.
I am not going to alter the colors, since I am personally still very happy as it is. (and it's an actual Tron color scheme)
If you are up to it, you could perhaps learn some skinning of your own, and adjust skins any way you want them to be. There's lots of information on learning that on the forum.
2. Since this posting of yours was not a wish, but a general question for help, I am going to move it to 'General' soon.
3. About your double click request; if every tiny specific alteration would need to be implemented for every person having such specific requests, it might be necessary to hire a personal programmer, and provide him with lodging, food and accommodations. (if you live in the Bahama's you might find one willing...)
Seriously, you could create a new wish for that specific request, but the timing for that currently is really bad, since there is currently lots of work being done to get v3 on the road. (and also I expect it won't be supported enough)
