Symmetry tool

I have been using Inkarnate to make maps for strategy games. I have been trying to make it as symmetric as possible, but I would like a tool to help in this.

I'm proposing to add a linear and radial symmetry tool. There should be an option to make the linear symmetry's axis an arbitrary straight line, and of course radial symmetry should have the "count" of symmetry in addition.

For stamps, a checkbox whether to auto-rotate and/or randomize the stamps would be good to have.
