I've decided to archive this library because my priorities changed a bit and I no longer have enough resources (time, money, motivation, etc.) for FOSS. There's a chance I might come back and start working on this library again in future (however, currently, I don't plan on doing that).
I won't maintain this library and it doesn't support Vue 3+, but otherwise it's still pretty usable (and if you're looking for horizontal scrollbars, you can take a look into development branch /docs/demotests.html which has some examples).
Vue 2 directive for custom scrollbar that uses native scroll behavior. Lightweight, performant, customizable and without dependencies. Used successfully in production on GGather.com.
