My main "problem" with liqbase is the small drawing canvas. With paper, I can use the huge 8 by 11 inch surface on both sides, but with liqbase I can't. It would be a lot better if the size of each sketch would dynamically change to become bigger or smaller, like a never ending canvas. And like vi or something, pressing a button would change it from draw to scroll mode. That would make it faster than paper.

Also, the fact that the "edit" and "view" screens are separate makes it slower. On paper, is basically WYSIWYG in a sense, but liqbase not so much.
