Very fun time waster - thanks! Two points of feedback that I had:
1 - Anchor the "Open # tabs" button to a static location - currently it changes positions at least three times (when upgrades or cache becomes available) and each time it throws me off.
2 - I really like the RAM usage bar visualization on the App Manager page and basically leave that up the whole time while clicking behind the window - would be awesome if that bar visualization could be added to the main page (either replacing the number visualizers in the top right or just in addition to them)
Either way I had a great time, so thanks again!
