i created a plugin, it doesn’t exactly do what you mentioned because you can’t trigger creating a note without opening the app,
but it does allow you to create notes quickly with a hotekey (suggested: ctrl + ] )
and displays your notes from the chosen source folder in a dashboard like google’s keep notes
No navigation, no thinking about organization, just write and close
you can read the README.md for more details
/rknastenka/Mini-Notes
The plugin is currently awaiting approval for Obsidian’s Community Plugins directory.
but you can try it out yourself:
on github:
/rknastenka/Mini-Notes/releases/tag/1.0.0
I’d love to hear if this matches what you were looking for
and if you have any recommendation or features
