Thanks Michael,

Ideally I would like to be able to have a random collection of objects that can be added/removed from a visibility group without impacting Object Grouping or naming. This might make more sense if I explain my current naming and my ideal (Groups working more reliably) naming:

For my example I will imagine a theoretical design project for a guitar capo. I would organize it now as follows:

Capo Static Curves <- Curves/Drawing
Capo Static Construction <- Solid Geometry for CSG
Capo Static Solids <- Finished Solids
Capo Static M3 x 8mm Pivot Pin Supplier ID#XXXXXXX <- Parts as assembly name then part name then manufacturer ID
Capo Static Spring 1mm Supplier ID#XXXXXXX
Capo Hinged Curves
Capo Hinged Construction
Capo Hinged Solids

If groups worked better I would ideally label as follows:
Capo Static (Group)
-> Curves
-> Construction
-> Solids
-> M3 x 8mm Pivot Pin Supplier ID#XXXXXXX
-> Spring 1mm Supplier ID#XXXXXXX

Capo Hinged (Group)
-> Curves
-> Construction
-> Solids

My projects usually have dozens of individual named objects and the scenario I find myself in all the time is needing to see how say, the M3 Pivot Pin and Spring interact with the Capo Hinged Group items. Right now this involves hunting around and toggling visibility for many items on and off. I would LOVE a hotkey for named groups to toggle them on and off.

The control key is a great tip, thank you! The large issues I have with groups are:

1.) Accidentally copying a group when I want to copy one object in the group. If the group is large enough (I have some 800MB projects with a hundred or more objects) this can cause the UI to stutter.
2.) Groups causing UI stuttering just by existing in a project.
3.) This is an issue with the latest beta and not only a group problem, but some sub-objects randomly turning their visibility on and off during project loading. It seems like visibility state is not saving correctly when projects are saved and then loaded. This is a V5 Beta issue.

As always, thank you so much for your help and for MoI!
Kind Regards,
