i'll be honest, i'm not sure what that's for? is it moving to another account if you want to change your home instance? if so, that's a good idea, i could add it to the post if you want in case this comment gets buried
spoiler
although i'm not entirely certain using https://github.com/Rob--W/cors-anywhere/issues/301 is a great idea..
i'm glad that's being tracked, as a bookmarklet is not really a great solution; but it's still not a complete solution. if i visit a lemmy post from outside lemmy.world (e.g. search engine), then there's no way to go to the l.w version (to my knowledge)
