Looks nice enough, but I won't ever again lock my notes data into a file format that is either private or too complex to in practice do much with outside of the app. I have lost too many 1000s of notes that way in the past. Exports are rarely useful -- losing metadata & structure, or not being cleanly importable into the next note system.

For now I use Quiver (http://happenapps.com/#quiver) which uses a documented json format simple enough for me to do anything I want with if/when I move on. It's mac-only, and development seems to have stalled, but I threw together a crude Android client for my own use.
