I mde a fork and fixed a few minor things for v5, but im a github noob so dont know what to do with it. Its here https://github.com/vfproductions/mui-theme-creator

@Zenoo yep nevermnind.. I already did that, and you completed it, and it's showing up here, so all is good. Just not used to seeing commits in ascending order. Weird

I did have one more small thing to PR, see https://github.com/Zenoo/mui-theme-creator/pull/4
