Feature request: First write the whole character, then hit "Submit" and see if it is accepted.
Reason: When writing characters on paper, it is possible to make a wrong stroke, quickly realize it, and then make the change ourselves. I would consider this a "got it" situation. When I am immediately told the stroke is wrong and shown the proper stroke, it is hard to know if I could have thought it myself, and therefore must always choose either "So-So" or "Forgot."
Same kind of thing when writing by hand in English. Sometimes I misspell words, not because I don't know how to spell them (well, sometimes because I don't know how to spell them) but more often because I am writing fast or simply make a mistake (such as missing a letter). I quickly notice and cross out/erase/modify etc.
Thanks.
