Short description of error
Collection naming and identification discrepancies between Outliner and 3DViewport
Exact steps for others to reproduce the error
When adding Collections via Outliner alone... seems fine... each newly added collection gets a sequential number and is added to list.
However, when Using the 3DViewport Menu options... Object/Collections/Create New Collection... the input box appears to allow a new Collection name to be specified... default simply says Collection... typing in Collection4 and hitting return does not add a Collection called Collection 4 to Outliner List... however, if you then select and object in 3DView and choose Add to collection Instance... Collection 4 is listed as available (even though not in Outliner.... Also Object/Collection/Add to Active Collection can recognize it as well.... but still the Outliner doesn't see Collection 4....
Thus items dragged in Collections are not updated as belonging to correct Collection in 3Dview, and 3DView has different idea about what objects are in what Collections that doesn't match Outliner organization... its as if they have their own database with no re-concilation or agreement... So how do the objects maintain proper grouping and layering and visibility, etc. between the 2 Editors? ... not very well.
Based on the default startup or an attached .blend file (as simple as possible).
