Screenshot and upload in one sweep

I wonder what you think about my recently developed application called Piclair Tool. I have one Windows version and one Mac version, but I
have put more development time into the Windows version so far. The idea is basically that you mark an area on your screen with one mouse click, and 1 second later your screenshot is uploaded to the web and you get the URL to it. I strive to keep the application as simple and efficient as possible.

You can fetch the application or read more about it here:
http://piclair.com

Anyway, I would like to know what you think about this application or about the service itself. Is there for instance any specific functionality you would like to see in the application? More functions will be implemented in the future.

Go ahead and try it, I hope you like it
