Great tool! Is there a way to add static text?
The 2 usability recommendations I would add are:
1) Tell me how long my video clip is. (Don't make me keep guessing if I am in the 5 second range).
2) After creating the gif, if I don't like it let me go back to the editing screen with the last settings I used. I trimmed a youtube video down in the editor, but when the gif was created a few extra frames seemed to appear in the final product.
