Increase undo action limit

[JustSlem]

Using your website I noticed that the undo history is very small (3 undo actions maximum).I think it's not enough for comfortable work, and if possible, I would like you to increase this amount.

@JustSlem The idea of this project was to stay as close as possible to the original version of Paint for Windows 95, which only had three undo actions. It's, of course, very trivial to bump this limit. Curious, are you using paint.js.org for serious work?

Oh, I've never used MS Paint for Windows 95 before, and I didn't know it was limited to three undo actions. As for serious work, no, it's more of a hobby. Sometimes I get tired of drawing in professional software, so I use paint.js.org as a break from all that. Also thanks for answering
