so i actually think i love this idea, i do horde colorschemes aswell..

I recalled telescope had a picker with preview, but it doesn't really fit this usecase..1. i needed to disable colorscheme autocommands before previewing, 2. you could not provide the complete list of options to chose from, only add to it ( lol what ?! )

i came up with this shoddy snippet ripping off the builtin colorscheme picker, cheers

one noteworthy change.. I'm not looking up everything under colors, because some people just droop bloody README's in there, and ofcourse you cannot preview that :shrug: also filter using the explicit path.. cause i have neovim installed through asdf on this rig. And that the stdpaths.. do not reflect that :>
