Actually that’s a fantastic idea. Should have thought of that for myself.
But as a warning, a lot of the Dracula themes are are not correctly (for some reason especially the Dracula Pro themes). For example the iTerm and Kitty theme have same foreground and background color set so I had to fix them manually. Doesn’t seem that they are tested by the author.
It would be useful with a public repository with [e.g.] solarized theme for “all” applications, the same way Dracula Theme has.
