For your first one, as a stop gap, my editor card can be modified to read & write the deck script:
https://codeberg.org/woodring/decker.whiteboard/src/branch/main/whiteboard.deck
search and replace:
deck.modules[w.module_name.text].script
to
deck.script
lines 71, 84, 96, 108
After editing the whiteboard deck, load it and cut and paste the editor card into your deck. Then, I’d have an offscreen button with a hotkey that takes you to the card that has the editor or last card. (though, you can’t have control+key hotkeys for buttons)
or alternatively
Modify the card to add four new buttons and copy the scripts editor.1 through 4. Attach them to the 4 new buttons that read and write the deck.script, instead, which retains the module editor functionality, too.
Totally stop gap, but the editor card is how I do live module edits. I flip between the cards with arrow keys and move it where I need it. That’s just my workflow, though.
