This is a great idea. I can see this being very useful for research and helping others with computer problems and troubleshooting.<p>I assume you are the developer? If so, I suggest you add a text tool, box tool, and arrow tool, because my drawing skills are crap and sometimes I just need to quickly highlight something or point something out.<p>If those features are implemented I could see myself using this a lot and saving myself a lot of trips to photoshop. Great Work!
