Since the objects are really basic, it's always necessary to start from
scratch to handle any data structures. I can later give a more complete
list of features (made one already years ago and sent it to Miller), but I
meant something that avoids repetitive tasks. E.g. "next 3" to jump to jump
3 scalars, or "index 10" to go to the 10th element, ... things like that,
that have to be programmed each time.
But regarding data structures in general, it would make more sense if these
could also go into Pd-Van (and with that libpd, etc.) - if not, then it's
better to just do some abstractions.

Could be a patch, but maybe easier would be a local html page which adapts
to any elements added to the extra folder, or even to Purr-D's path (would
also be easier to search). All that meta information in the libraries is
just sitting and not being used.
(again, would be good to be Pd-van compatible)

Regarding searching, I'm not aware of the latest state, but a couple more
details:
- seach window says how many elements were found ("x of y"). Maybe this was
in already.
- (also from max) when a variable is used in send/receive, clicking on that
object opens up the subpatch where the matching send/receive is. Fast to
find, and avoids repeating variables. Also for send~/receive~ +
throw~/catch~

Not sure, because as I understood it, gen patches work on a block of size
1. So it's like writing C code. The number of classes is much smaller, of
course.

If I get to do something more in Purr-d I could get more ideas to ask (I'm
trying to prepare some materials for the LAC, so it would be a chance for
it). But I have some issues, that either purr-d doesn't work on my desktop
(it just doesn't start), or some things I need don't work as good as in
pd-ext (data structures). If the workshops I'm proposing work out, I can
try to push them to purr-d
