When the object list is longer than the visible list there’s a scroll bar. When dragging an object to move into a non-visible collection, I expect automatic scrolling when reaching the top or bottom edge of the list. Like in Windows/MacOS etc. Extra plus if this scrolling starts modest, and then accelerates after a while.
Thanks for suggesting the idea related to the Outliner. Please see here GSoC 2019: Outliner Improvements Ideas. Majorly Outliner idea and development are going there. You will be respected there. Please.
Yes we need this really. i don’t know why blender developers forgot to implement this option !?
