Thanks for replying. I've tested a couple of things but haven't had luck yet passing a file without first exporting the note, but it's not a deal-breaker so I haven't dug in too far yet.
I've built a todo extension that will read my .py or .txt (or whatever) files from the share sheet and create reminders and tasks through ClickUp, so I can keep track of my project work a little more easily. I've never thrown my code up for review before, so if anyone is interested in taking a look, feedback is appreciated!
