I have the desktop version on my main PC, but I'm on my Chromebook and wanna use Mystic! I can try to build it if I can find the code and host it on a website.
i made a sandbox (not as good as mystic) at https://treeplate.damowmow.com/explorer/#/
(and a discord for it at https://discord.gg/2qxVQAE94z)
