I think this happens if you type out the full link without selecting anything? I usually select something from the suggestions and never close it manually.
Eduard Metzger: The key phrase here is “when creating a link to a page that does not exist". Yes, I've typed the full link. But I'm typing a link to a NEW page, so I HAVE TO type the whole thing. Basically all I ask is that the helper CLOSE when you hit ] or ]] so that hitting ENTER thereafter gets you a newline as expected rather than replacing the contents of the link just typed.
Jon Plummer: Ok I understand now. I works on iOS but not on Mac. Have noted it!
Eduard Metzger: You'll note also that the matching is a little odd – judging from the screenshot above. That said, I use the heck out of NotePlan, every day. So I'm obviously very happy with it.
Jon Plummer: Thanks! Yes, the matching uses "fuzzy search", means it doesn't look for the exact match, but widens the results a bit to include typos and similar things. Sometimes this looks very odd.
Here's a screenshot showing that I've closed the link and the selector remains open with something irrelevant selected. It would be nice if ]] closed the selector.
