Hello, all. Instead of creating a new topic, I’ll just amicably hijack this thread!
First of all, thanks to @Ace_Dragon for explaining how to move objects into Collections. Not at all intuitive if you consider that the new tree-oriented Outliner with its Collections now effectively replaces the old method of layers and groups…then again, following the old “logic” it makes perfect sense!
What doesn’t make sense is that in the Outliner, you can drag-and-drop objects into and between Collections…only if they are close enough to be dragged-and-dropped! If the Collection is out of view, the Outliner window won’t scroll to the target with the selected objects being dragged.
Secondly, the M key only works in the Viewport and not in the Outliner window, nor is there a contextual menu in the Outliner to move selected object(s) to a Collection.
Yeah, I know Blender’s interface has always been…eccentric. For the last 10ish years I’ve had no real problem with it; it is what it is and I love it anyway. But with the new 2.8 interface trying to be more “industry-standard” certain things about it just fool you into thinking it’s changed, for lack of a better term…and we’re pretty close to the July target.
