I asked once about this - there's IIRC an alternative editor that supports this on desktop, but I'd like it generally.

I think some of this comes from some people making really long notes, and some people not - I remember a precursor note-taking app having a broken in-note search function as well, and when I reported it the developer said something to the effect that it's not a valid use case...

I hope they figure it out eventually - pasting notes into sublime text just to do a search is a bit silly ...

(The developers generally are pretty helpful and earnest about their app, I've been a paying customer for a few years now and am happy with the app for the largest part)

Same. I got into the workflow of copy/pasting long notes into TextEdit so I could ctrl-F normally. It began to feel so outrageous that I was paying for a text editor and had to resort to a workflow involving a second text editor for a fundamental text editor function that I finally came to my senses, exported my notes, imported them into Obsidian, deleted Standard Notes and never looked back.

I left NotePlan when the author doubled the price to $120/yr. I didn’t want to get too wrapped up in a platform that randomly jacks its price so much.
