+(snapshotting being "where you have virtual thumbnails on the printed page to represent all the programs, so they're still pointable & have regions etc…
+the thumbnail regions could all be captured from table session when the snapshot is taken (& shrunk down to fit on page), or i guess they could just be a grid if you have a statement that is just a straight list of program numbers like you propose?")
+>> Could you have a separate process that journals the holds and writes to disk on crash or quit?

+Notice the blinking of the editor -- this is extreme (other slow stuff is happening on the table), but it happens occasionally even while just normally typing/backspacing:

+Tracy view when I type a bunch of stuff (see the blips on the keyboard thread for when I'm pressing keys) and the editor blinks out (see the dips on the plot at the bottom):

+I did optimize the editor a bit by [[https://github.com/FolkComputer/folk/commit/a88d925f541efde46169e55ad9828620232d5f5f|decoupling cursor state from rendering]], so it only blinks when you actually edit the code, not when you're moving the cursor. (It's cool how just by separating your logic into different independent Whens, your program feels like it gets more and more parallel and reliable...)

+Omar: Mason and I spent a while throwing around ideas in Discord about how to share objects between threads (separate Jim interpreters) in folk2 without copying/reparsing (which is what both folk1 and folk2 do now, although it's a more acute problem in folk2 because stuff comes fresh out of the DB for every When execution)
 ('immortal' is [[https://peps.python.org/pep-0683/|a term from Python]] for what I think is a similar concept)
-I think we have an OK plan for this, actually, and I [[https://github.com/FolkComputer/folk/tree/osnr/folk2-transients|started hacking on it]], but haven't really fully implemented it yet. Something to keep in pocket if we need it, maybe.
