Please add a setting in preferences to always "copy" any snipped image. This would make skitch so much more usable, convenient and fast.
Every time I use skitch, I do the following:
select the area of the screen to snap
snap the image
hit Ctrl-v to paste the snapped image into an email or doc.
This fails because skitch doesnt copy snipped images by default.
Go back to skitch.
SEarch for, and navigate to Edit->copy Image
Got back to my doc.
Finally can hit paste.
This is a pretty major missing feature which make skitch extremely painful to use, and only needs a few lines of code to make it perfect (for me and probably thousands of others).
