Same here - no more than 2- post for mouse scroll.
I agree, mousing around long threads is a terrible thing to do in discourse software but you can’t use the almost hidden, tiny, obscure, nearly invisible scrubber on the right?
Yep, you are right. The “problem” is that I have to move the cursor exactly over this scrubber to “select” it. Which is not the same as using the MMB or directly switching to desired page of the thread.
With mobile devices its become even hareder to use this scrubber.
