Nova Launcher got bought by a data mining company a couple years ago. I left and went to Total Launcher. It is a little weird at first the way it works, but it is now my full time launcher.
I like it for the over lapping widgets that can be sized down to the pixel. It also has a bunch of built in widgets like icon widgets and allowing widgets to stick in place across home pages.
chromeos is the correct answer. It maintains itself. Also, using gdocs, gaheets, etc., you dont have to deal with backups, “lost files”, etc.
