Hello there,
I am looking for a way to open a specific note from my desktop. So when I click on the shortcut on my desktop it should open a specific note in joplin.
Right click the note and select "Copy external link". On the desktop right click and select New Shortcut. Paste the link there. Give it a name and you're good to go.
Works fine on my Windows 11 box but since it opens the note by using the noteID it is limited. Having a profile running that doesn't have that note just gets whatever note happened to be last open. It may be limited to Win 11 and installations with only the one profile. It would be useful to do as you asked but with multiple profiles, that's a pretty difficult task and probably not what anybody would want. Changing profiles when a note shortcut is clicked would introduce issues.
