Didn’t have time yet to watch all of the video, but on my own GrapheneOS device, and assume especially useful on tablets, I have been using Molly for Signal messaging.
Its cool because I can use an existing account (already attached to a phone number) so the device doesn’t require a SIM. The normal Signal app does not support this.
Unfortunately at the moment I am having to use “Molly” not “Molly FOSS”, meaning I have some of the proprietary blobs in normal Signal app. It is currently too much hassle (for me) to setup notifications with the FOSS version.
