At this site there is a little panel where you can draw a kanji, and it will look up the kanji based on your stroke order and stuff. Now, of course its not very helpful for when you are doing your reviews here if you have to keep opening up a different window to check your stroke order, right? So for awhile now I have been trying to figure out how to sort of integrate this more easily with my normal reviews here at this site.

I tried various things... spent a lot of time trying to learn how I could turn it into a firefox extension or something... but it was to no avail. But then just now it hit me... all along I've had the solution right in front of me!

There's a great little firefox extention called All-in-one sidebar, which I have been using for a year or two now. It has a feature that lets you open any webpage in a firefox sidebar. So now I guess you can see where I'm going with this! You simply open up the handwriting recognition in your sidebar, and you have Reviewing the Kanji open in your main tab. As I go through my reviews now, I can just quickly jot down the kanji in the drawing panel, and if the kanji I was trying to draw shows up, then I know I got the stroke order mostly correct. It works really great!

The windows IME has this feature as well. Go to Language Bar > IME Pad > Hand Writing. It also has the critical feature of reverting back a single stroke, which is important for 12+ stroke kanji so you don't have to start over for a single mistake.

And I don't see how this helps with stroke order. It identifies them even with the wrong order.

Hmm, well I don't have a pad available in my ime for some reason. I've tried reinstalling and everything before, but it just doesn't show up for some reason. And while you are right, this doesn't show you for certain the correct stroke order, it does let you know if you are at least in the right ballpark. Also the kanji links that pop up from it just puts you a click away from seeing the animated stroke order.
