This has been on my TODO list for a long time, but do not trust my TODO
list. The next thing I do is more Mac support, upon special request, and
then I work on one video performance project, and then I'd like to find
time to work on GridFlow features, and there are about 100 features that
compete very well with GEM support.

But by mentioning it, you are raising the chances I'll do it soon. =)

Just a quick note: loading PDP, GF, GEM all at once in PD, is loading 47
shared libraries at once. It's nice that it doesn't crash. I'd expect some
shit involving signals. It is more likely to happen once I try doing real
things with all three together, but I don't know yet.

For now, what you can do is use [@export_list] to convert GF grids into PD
lists. I suppose that "GEM support" would involve making a faster
link? How slow is using [@export_list] for this?
