Tomboy is still my note taking program as in the homepage of Gnote I still read: Synchronization support is being worked on, and sync was one requirement when I chose a note taking program some years ago.
I use Ubuntu One as “cloud space” for my notes and so far it has served me well, so also if Tomboy is a mono program I’ve decided to continue to use it, but how to configure it on Mint to save the notes on Ubuntu one ?
