I switched from Jerboa to Liftoff after every singe update they introduce breaks something new and they don't fix existing issues. My current biggest issues with Liftoff is the very un-smooth scrolling, that hard-coded bright blue, and that you can change font size for headers and sub-headers, but not general text. I'd like it to be 1-2 notches larger, on a phone with large display it's getting a bit small.
