A while ago I released shup, the latest client utility for stashbox.org. shup makes it easy to turn any window into a pasteable url in moments, using a simple keyboard shortcut. The basic workflow is as follows:

1) User presses the customizable hotkey.
2) Screenshot of active window is saved to a PNG image.
3) PNG image is uploaded to stashbox.org.
4) Resulting URL is placed into the user’s clipboard for access.

Pretty easy! Check out shup here. =)
