> No ads, ever, I hate them.

Thank you! We shouldn't trust anyone who thinks otherwise. It should be considered shameful to show paid advertising.

Do you hate any type of ads? I see great potential in having service app options that do not seem to me to be very harmful, but I may be wrong... For example, when I mark that I had dinner with my friend at a Japanese food restaurant that I really liked, I could not have an option to book a table using an app like resy.com. Or yelp to find a different one? Or when I note that the last time I was with a friend, it was in a movie theater and this week will launch its sequel, a link to redbox.com. Or in the case of a band show we like, link to ticketmaster?

It does not have to be something that makes it difficult to use, an icon at the end of the note could be enough.

"The paid version will contain some great features, and will probably be a couple of dollars per month."

Forgive my ignorance, but with the code under the GPL license, how can you offer exclusive features?
