One problem with mobile that I've been noticing is that signatures are still scrollable, even though they don't have a scrollbar. This might be behavior specific to my device, but when I am scrolling through the page and happen to scroll on the sig it scrolls that instead. Is it possible to make the sig area enforce the px limit itself and never contain more than the 200px/whatever it is that is allowed?

ALSO: The post writing form needs to be able to scroll. It [i]can[/i] be scrolled, but it is clunky and not easy to do. Could a scrollbar be added when necessary on small devices? I'm not sure it'll fix the issue but it wouldn't hurt.
