From the developer:
Hovertino is a note taking application. The program provides windows that actually float, glide, hover, move out of your way, yet remain always visible. After you first run Hovertino, you’ll be able to right-click on selected text in any app on your Mac. Hovertino saves all your notes automatically and provides a sleek and unobtrusive way of searching, editing, and deleting them.
