I would use Cinta much more if it had this feature. I keep notes of what I need to do as well as general information. I would also request that it is possible to delete the note when the reminder pops up in order to keep the note book clean.

Perhaps while you're adding in timing feature you could add in note expiry time. Couldn't find this mentioned elsewhere. For example, I might keep a note that there is a trade event coming up on 5th June, I do not need to see that note on the 6th June. It should be possible to auto-delete.
