@christopher_bahr Thanks for looking into this despite it having only a few votes. I think up to Revit 2020, the Autodesk C-Cloud had a kind of short cut or project pre-selection before you actually changed over to the ACC screen from your home screen. After that version it was always at least one more click to be done. So yes, I would still propose to have a button to manage the current model.
Also I could not find a way to tell who is currently busy with the model which is what usually makes me fiddle with the manage button in the first place.
These ideas on this forum need not necessarily go into next years version. I would not mind having a button of this kind in R19 (which is currently the lowest version I still have to deal with). I checked the 'new' manager in Revit 24.0.20.20 which is still an unupdated release version I think.
