Jesse, I've fixed the extra whitespace on top and on the right end side, removed the blue line in the tabs, reduced the content indentation a bit (otherwise it will look odd later, I'm sure), and I've moved the donation button to the right upper corner. So, please do a git pull before you commit/push (or submit) the changes.
What remains to do is moving the tabs including content up to the pink area. I'd be interested how this is done in Pyjamas only... :-) Can you try? (Would you do it with CSS only?) Cheers, Peter
