Custom Scrollbar implementation / Prevent white scrollbar on black themes

[adammesa]

I think this may also be part of a feature request, but I would like to ask for the implementation of, or documentation for adding a custom scrollbar to the code editor - the white scrollbars on a black theme really hurt.

I think it's also worth mentioning that the browser scrollbars are massive, and needlessly take up space (especially noticeable on my already cramped code editors).

I'm currently using ng-scrollbar, which allows me to add the ng-scrollbar directive to any normal element to immediately implement the scrollbar, which unfortunately does not work for ui-ace. 😭
