Create links to notes by typing
@@ and selecting from a popup window.
Based on the same idea as Plugin: inline tags - #3 by uxamanda
Shows 10 most recently updated notes initially, then as you type it uses the text to find notes with matching title.
Still a bit rough (e.g. will offer to create a link to the note being edited), just trying to see if there's any interest in developing this further.
The plugin requires Joplin 1.7.x
