I agree. I have been using Ruby Motion since it came out and have released a few apps. I am a little worried that Swift will squash what momentum Laurent was able to build from MacRuby to Ruby Motion.
Outside of implementing the notifications this offers nothing for me that the original one, from James Fator, doesn't already do. I dislike the table display and the attempt at making the appearance be more Cocoa-esque in favor of the Google web design. You might also want to think of changing the app name and icon also as it is misleading.
