Perfect timing too - really didn't think it was that close to releasing. Still wish you could remove a number entirely, regardless if it can be hidden or not. Maybe once out of beta that'll be an option. Promising.
SimpleX has grown on me though.

I love simple X
Incognito Mode Etc
But totally Signal Needs to remove the Phone Number Aspect if they want to get ahead. I tried getting into the Beta On TestFlight for IoS but no more links available till the full version is available
