Enhancement: Remembering position in reference lists
When switching between collections, the list views should remember their positions. Currently, each list view always comes up with the first list entry in the topmost position. I find it quite annoying that I have to scroll down again and again after checking whether an entry from "My Library" was in another collection.

This makes my suggestion a low priority item. According to the priciple of least surprise, it would still be nice to see it implemented some day because most other software behaves this way (remembering the position/selection in a list view).
