I'm using it now on my S2. Looks really good. However, I don't seem to have an "enter" button for creating new paragraphs etc which I did have on the old version?
If you're replying at the bottom of the thread press the + that's within a circle then you're able to use enter.
When you quote someone this goes to the same editing screen and enter is visible also.
Yes they pull the app once the testing is done and it will no longer work... It redirects to a paid app
