The new commenting feature (0.1.28) is pretty awesome. I've a couple issues though:
It only works on answers, not on questions.
When you tap the "add comment" button, the keyboard and the textfield that pops up can cover the whole area you were just reading. This is specifically annoying for the add comment button on the last answer in a list.
My suggestion: push the bottom of the screen up to above where the keyboard shows up. Basically, scroll the visible portion of the screen to the bottom of the answers list. (There might be a better way though.)
There's no way to remove the comment bar if I change my mind and decide not to comment. Perhaps an
x
or a swipe down?
