I admire the elegance and light-weight design of unforget.

I'm a Google Keep user as well as a Notes user. Keep doesn't support end-to-end encryption and Notes doesn't yet support syncing between multiple instances. I make heavy use of the folder functionality supported in both apps.

I read the thread on Hacker News explaining why folder support was not implemented in unforget.

Although I really prefer folders, I could almost get by with hash tags in unforget except for one thing - I can't think of an obvious way to list all the distinct hash tags in currently in use. You would have to memorise the ones you have used.
