Hey! I've been doing some work to make mousewheel scrolling speed more configurable :p
I've tracked the feature to finbars dependency (didn't see anything being triggered in ThumbwheelScrolling.js).

Two new properties were added scrollingHorizontalMouseWheelMultiplier and scrollingVerticalMouseWheelMultiplier, which are proxied to finbars.

These values can be set as:

• between 0 and 1 -> decrease speed;
• 1 -> original speed (default value);
• above 1 -> increase speed;
• negative values will invert the scrolling (could probably apply a modulo on this?...)

I'll open pull requests for both repositories for you to test and comment.
Thanks!

@hugoeanogueira Did you test on Windows and Mac? Additionally, any thoughts into delegating the event from the ThumbwheelScrolling feature chain as opposed to from the finbars.

[hugoeanogueira]

Not yet, I need to get a Windows machine first and do some testing.
I've tried to do some debugging in ThumbwheelScrolling.js, but haven't managed to see any action in there. Maybe I have to configure anything for the event to be propagated to the ThumbwheelScrolling feature chain?
