@nice work 
Small issue I encountered: currently I cannot make the app work if I use the ublock origin configuration detailed here by @lightyear: the authentication popup from the launcher never triggers,
As soon as I disable it though things work fine.
Could this mean that your app contains some links to clearnet ? and if so do you have plans to remove them ?
Edit: My bad it works with this ublock origin config:
||$domain=safenet
@@||safenet^$domain=safenet
@@||localhost:8100$other
@@||127.0.0.1:8100$other
The one I used before was blocking http://localhost:8100/auth which caused my issue. All good !
