self-deleting notes (after X time?)

[WPFilmmaker]

Hi, first of all thank you very much for your work on simpletools! As per title I would like to request the ability to automatically deletes notes after a certain amount of times (could be minutes,hours,days). Often you need to keep notes just for a limited amount of time, then they can be discarded. An example could be a note about a meeting, after that meeting it is likely that the note is not useful anymore. To avoid having lots of used notes and to declutter the interface I think it would be nice having an option where you can specify the lifespan of a note. Thank you.
