Great job so far, I think this is a near perfect implementation. There are a few small changes I would make.

1. Have the boosters next to the turn order, or at least have more of a description on the on passing options so you don't have scroll to check which booster you you want to take.
   Maybe if the Feds and boosters were separate with the Feds going beneath the pw actions.

2. The change to turn off/on planets having their original colour is great I just wish the ring around the outside was a little thicker.

3. Automated power charge, someone else mentioned this.

When passing there is no description of the boosters it would be useful if it showed you the tiles themselves so that you know what you are picking, I find I am constantly scrolling back and forth to check and double check that I am taking the correct booster.

Oooh one more thing

4. Allow players to have a flag next to their name so that you can see approximately what time zone they are in. If you want your games to be as fast as possible then having everyone in the same time zone usually helps. Or have the option to put that information into the game setup options.
