Is your feature request related to a problem? Please describe.
it's always frustrating when you try to scroll a lot but can only do so slowly via the scroolwheel, for example in the Computer Manual or the Control Unit.

Describe the solution you'd like
Make the scrollbar click- and dragable
Adding a scrollbar to the different chapter of the Computer Manual would also make reading them more convenient, especially when the above feature is also added

Describe alternatives you've considered
suffering

Additional context
This is default behavior for similar Minecraft scrollbars, I think
