I just got Grabbit. I like it (so far) even better than I liked Skitch! Setting the captures to go to the clipboard is SO much more convenient than having to drag them. YAY!
OMG what did Evernote do to skitch? It feels like they made a list of everything that was great about 1.x and then removed it in 2.0. I have trashed 2.0 and reinstalled the prior version from their website.
Here is a link to an interesting article, it also contains links to download the previous version (1.0.12) and also a link to a "how to" to stop the App Store from reminding you to upgrade (if you haven't already done so).
