Nice! Let's use something like that! I think the one on the bottom left looks nicer, as the black lines are distracting, but if the black lines are made a shade of gray, it should work too.

The way rows and columns apply to groups like P4G or P6M is strange.

To be honest, I never understood how those work. It never came out right for me. If anybody has a tutorial to share, please do. :)

Since there is a lot of space in the Symmetry tab, we could add a link on the bottom titled "Documentation," which pops up a symmetry tutorial. In my proposal, the visually selected boundary path can take any angle, so the tutorial could tell you which best angle to use to get the desired results for that type of tiling.

But maybe things are as they are because of the structure of SVG?

I haven't thought of that one! Can someone confirm whether this is the case?

Apart from that, does anybody else have the pros and cons of having only clones? (you would not be able to "remove" all the clones leaving only the original, but "undo" also works no?)

Exponent has no unit.

Thanks! I'll remove it from the mock-up.

BTW, I'm not sure how Randomize works. Would 5% mean that the range of possible deviations is from -2.5% to 2.5%? if it's something else, it might not make sense to offer absolute units there.

I could see a use for absolutes in randomnize though. Let's use the example of shifting: your clones will be able to shift in either direction by up to 5 pixels, thus introducing variety without going out of certain bounds. Like this:
