Notifications

[Nihmar]

Hi,
First things first, me and my wife are loving your app, truly exactly what we needed for our busy home life (no more post-it!).

I just saw the release 0.20 and I'm amazed you are cramming so much features in such a short amount of time.

Now, as per notifications, would you consider adding a section in the settings to customize them?
I was thinking that one could also set to send notifications via email (I'm thinking of SMTP) and/or an integration with something like gotify (which could be selfhosted as well)

In any case, thank you again. If I knew something about JS in a meaningful way, I'd be happy to contribute, but I'm a Python and Delphi guy (with a bit of rust)
