Bear has such a feature. You can archive a note and it’s gone from the list, search, … If you ever wanted to see it again you can select View -> Show Archive and you get a list of archived notes. From there you could Unarchive it and it shows up in the original location.
As Dor said, you can create a folder named “Archive”. To make it appear at the bottom of the list, I precede the word “Archive” with the Chinese character “one”, like so:
一 Archive 一
Using an Archive folder is really not ideal, because other features won’t consider it.
For example, graph view will still show “Archived” notes.
I imported a thousand notes from Apple Notes where I used that pattern of having a global Archive folder, and also inner Archive folder inside other folders.
