Option to treat view-once media as normal media. Option to ignore remote deletion. Choose between FCM or websocket notification delivery.
nice what you added, but you should look at the work of Molly.im which added a lot of functionality in addition, (call that erases etc etc), why not work from the fork of molly to improve your side?
As long as Molly does not receive notifications when its database is locked it is not usable for me as a daily driver. Further I want to keep the changes to the original Signal code limited to reduce maintenance time. Maintaining Molly against new Signal updates is a lot more work for which I have no time available now.
