Hello, I'm interested in implementing a system-wide call/number blocking feature (re: https://github.com/ubports/dialer-app/issues/18, https://github.com/ubports/telephony-service/issues/43).
I know what I would like from it:
- contacts app integration
- call blocking
- sms blocking
- ability to see history for blocked numbers
- ability to easily block a number after the call
But I'd also like to hear what the community wants so I don't miss anything, so let me know.
THIS IS NOT A TOPIC TO ASK FOR PROGRESS, NOR WILL ANY PROGRESS BE SHARED HERE.
Please stay on topic and post what you need from such a functionality. Asking for progress here is pointless - once I have time and have something you will definitely hear about it 
But this feature should be integrated into the OS though, so that's what I'm going to do. SailfishOS's ofono fork will help a lot.

buuuut we did figure out that Pebbles work fine on focal, the issue is in the RockWork app and it would need a reimplementation - probably less work for me to add Pebble support to mine once it actually exists.
