I kind of see the utility of having screenshotted rects remain visible. I personally will stick with Cmd+Shift+4 since it does the screenshot-with-bounds and saves to desktop by default. Maybe I just don't see what the extra value is here?
My same feeling. My girlfriend and coworkers love Skitch. I just use Cmd-Shift-4 and Preview when I need to add some arrows or text to a screenshot. Need to upload? Dropbox and "share link." Of course streamlining it is okay, but not for me.
Automated upload instead of having to use Dropbox.
I've used Cloud app for this in the past - works great, but has an upload limit. What's the story on that here?
