Wick looks like a great start to finally filling that huge, gaping hole where there should be a tool. Thank you for creating this. I hope it becomes hugely popular and quickly becomes a polished tool.
I have bookmarked this and will definitely be using it the next time I have my kiddo at the computer so I can show her how to make something move on the screen.
Increasingly, I find myself perfectly happy to use online tools for certain tasks. I'm a huge proponent of having local tools, local file storage, and for desktop computing in general. But there are amazing convenience gains to having browser-based applications. That's doubly true for this since the delivery platform is also the browser.
