2 things.
1) much better name for a matrix client than the others, Nova sounds cool.
2) $10/month is more than Disney+ per month. Could there be the option to accept a $5/month for desktop only and a separate $5/month for mobile? Then a combined $10/month for both?
Massive kudos on it looking good (even if electron) and doing Matrix stuff nicely.
I will be watching this closely, especially when Signal is ready to go.
If you don't want to pay, you can always spin up our entire system on your own server. One way is to use Matrix-Docker-Ansible https://github.com/spantaleev/matrix-docker-ansible-deploy It is finnicky though. If you promise to give me good feedback and bug reports, sign up for the beta and I will waive the fee though!
