Hey @Keavon! My quick reading of this topic could very well be wrong, but…
I’d say consider “Ctrl-G” as a hotkey to be reserved for future use. It is certainly bound to a broken thing now, but the potential of that future feature is considered important enough to keep that open for it. Not that I would expect that feature, probably Common Groups like the “Object Grouping” we used to have, any time soon if ever. LOL
For improving Collection Grouping I’d give some hope for this summer since we have @natecraddock back working on the Outliner again.
