StyncyNotes app
Sticky Notes + SyncThing = StyncyNotesStyncyNotes is a simple Sticky Note application that supports some basic formatting features like those available in the linux mint "Sticky" application (see https://github.com/linuxmint/sticky).
It stores notes and formatting in a simple local json file that takes the same format as the linuxmint Sticky, so if you happen to run this app on your desktop, you can use SyncThing to keep the two sets of notes in step.
