The Animator

I'm sure everyone gets these but why doesn't anyone point em out.

1: When I click the fill tool it will undo certain lines.

2: When I make a new layer it undo's certain lines.

3: When I click literally anything it undo's the lines.

Also I think the option of turning off onion skinning would be a really nice feature

so ur literally saying if you blink it will undo certain lines

indeed.

hmmm so it only works for me?

Sometimes if you drag a line off the canvas, the line won't be counted. So, if you're ever unsure about the line, just add a quick little dot.

Yep
