[Feature Request] Per-Device Settings like A2DP

[citizenserious]

Hi pilot51,
first of all thank you for your work. You created a great FOSS app.

Feature request:

It would be nice to have the possibility to choose on which BT device a voice notification is triggered.
For example, wearing headphones or in the car but not while using a bluetooth speaker with your friends.

A2DP does this, by letting you activate single bluetooth devices.
Unfortunately the app has not been maintained since 2019, and its original use case was not voice notifications, so it is not working reliably anymore.

Related issues:

Could probably solve #45 and #44
