Yeah I was like no thanks

honestly - if you just copy/use the three column design and color scheme from Reeder this would be damn perfect. I find the 3 column design (like mail, reeder, messages (ok thats only 2 but you get the idea) to be perfect on the bigger Mac screens.

I have 0 idea how hard this would be though.

Great start. UI def needs some tweaks (maybe it’s just the colors chosen?) but better than I can do lol
