I use Skitch all the time. However, I've been really unhappy with the continuous "The sync operation cannot complete because you have reached your monthly quota. Upgrading your account will allow you to continue your sync with a higher quota." I realize the answer is to upgrade, but what really bothers me is that I KNOW I've reached this quote, yet every single time I want to use skitch, I use a lot of single screenshots, that immediately get dumped, I have to go through multiple steps, because there is no way to say "Yeah, I know, I really don't have to walk through the whole 'you should upgrade' process, which is not quick. It's annoying. And it's annoying enough I've been quitting the application because if I don't, the message continually pops up, even if I'm not using it. You're making this very irritating.
