Thanks for your feedback! You can use the "New Canvas" button / option to start off clean: https://imgur.com/JHsI61W

We are re-structuring various sections of the interface to make that options more apparent.

Thanks!

It would be nice to have a way to just clear the drawing without randomising all the settings. That's how Weavesilk works. There should be a seperate "Random" and "New" button.

Also sometimes the Undo button just doesn't do anything and gets stuck highlighted yellow. I'm not sure how to "unstuck" it and get undo to work, so instead I have to refresh and lose all the settings.

Thanks for the feedback! The reason why we mix up the settings is to let users play around with predetermined arrangements. We think that that is cool in certain circumstances. But we also agree with you on the fact that separating "Random" and "New" button is a good idea.
