Once the DB refit is done, I vote that basic clipboard text and perhaps rich text copy/paste functionality be implemented for whiteboards first and foremost.
When I had to quickly put together a signed document on a friend’s PC, which happened to have Logseq installed, I didn’t even bother to open Google Docs or see if MS Word/ Libre Office was installed. The whiteboard feature is just about powerful enough in a pinch. The only snag was that it didn’t render markdown as I expected, and I was unable to copy/paste basic text.
Other than that, it is an absolute life-saving feature (at least in this instance) and has tremendous potential.
Edit: unfortunately I cannot include the document for security reasons
