You've already fixed quite a few. Back button now takes you back to where you were (instead of the beginning, then needing to scroll). I had trouble with seeing previous comments when typing replies (now I can reference while typing). :)

The cat licked its butt.
it's = it is
Read it aloud in your head. If "it is" does not make sense, use its.
p.s. I had to correct autocorrect twice while composing this twetch.
