Simple and easy to use addictive tool. It makes the process of screencapture an interesting thing, as you can edit the screenshots right in it.
the internet is all about having fun unless you work in the web-industry, and Skitch delivers. if you check out the shared photos on the program's home page, u'll definitely find heaps of nice pictures.
Since i downloaded Skitch I haven't made a single screenshot without editing it in this program. i don't think it's a must-have cause you could easily do without it. but if you download it, you'r gonna use it on a daily basis.
