5.99 group editing

This whole grouping thing is quite new. It is a feature only in KiCad-nightly V5.99.

For this recent thread:

I also found a way that did what OP wanted, but it feels like the functionality of editing and/or working with groups can be improved.

With groups you also have the problem that it can contain different sorts of items. For example, if I select a pad and then press e for edit, I get to edit Pad Properties:

… and if I select a track and press e for edit, I get to edit Track & Via Properties:

However, if I select both a pad and a track and press e, then KiCad appears to get confused and it does not know which dialog to show.

I assume that the grouping is just a method for making the group, and it only affects the way things get selected, and it does not change the way that operations on a selection work.
