I think Physical design reuse (PDR) is far out of scope of the group
selection idea. However it Might be used. I actually put some thinking
on howto implement some kind of PDR into Kicad without having to
redesign everything existing already. Its in a google doc with comments
enabled.
[Google docs link]
https://docs.google.com/document/d/1ivRRu7F2g6_WU9bgHlaUTaXZw02oluMh4NA41BqEM-8/edit?usp=sharing
PDR discussions I think should be in a separate thread, since the amount
of work to get there is quite a bit more, involves both eeschema and
pcbnew, new file formatting, specifying workflows etc etc.
Its called snippets in A****m, PDR in PADS.

Hello!
This feature looks really useful in production if it's implemented properly.
Some comments from my side how things could be extended in the future:
Group selection (also read: table-based/parametric-based selection!) seems like
a great feature and the step towards physical design reuse (PDR).
With some intelligent grouping of routed components and automatic/assisted
selection of components based on netlist-topology (or manual or table based
selection) it is possible to create a physical design reuse (or channels) by
duplicating groups with the same layout but different component references +
different net names / instances of net names.
An additional approach is intelligent "group editing" (table based - a must
have for complex designs!) where there is an automatic / assisted rename of components
and netnames to create reuses. This also applies to the schematic entry, obviously.
The word "intelligent" above means obviously, that there is some infrastructure
and coding work to consider.
An example screenshot of one of my designs using a buggy commercial product is
attached. There are 60 similar channels.
Layouting these manually would be a hell of work, obviously.
Regards,
Clemens

I think this feature would be useful but we should proceed with caution
if we are going to include persistence. I'm guessing making groups
persistent will require a change to the pcb file format. We should
think this through thoroughly before moving forward. Is it possible
that this grouping could be used for an a****m like room feature? If
so, than we need to plan this out accordingly rather than just commit a
new feature for the sake of convenience.

I like it. Give me a few days to review it and I hope it will get
merged. You'll also have to make the groups persistent (save to file).
Recursive grouping (group of groups) would be also an advantage.

Hey again, What would be the chances of seing this getting into the
master branches on launchpad, what would I have to add/change to get it
there?

Hello!
I hacked together a group selection concept looking like this:
https://youtu.be/eJp-aJ8i0H4
It can assign BOARD_ITEM to a specific group for easier selection and
group manipulation. I am open to suggestions on changes, this is surely
not an optimal implementation.
Useful when you may want to keep the relative position of something on
the board like maybe a RF layout etc.
It cannot currently save the group assignments between sessions, since
that would require some changes to the file format. That would need some
agreement that this is indeed wanted.
it also doesnt work on zones right now.
ps: I do not now the best way to attach a patch file.
I added my feature
commit
git pull
fix conflict
commit
Anyone have any steps on how to get one patch file for this, now I got
one patch file, and a merge.
