When you open Font Features window (Character>Font>Features) and scroll down/up using mouse wheel it's too much slower than the speed of scrolling in other parts of Writer (e.g Font list).
Try with the attached font that has many otf features to have long list in Font Features window.

Caolan, may be you could increase a mouse wheel scrolling speed in this case as you made it for Conditional formatting dialog?
