It would be interesting to know, by the developers, the reasons why these features were not implemented. Maybe I’m wrong but It seems to me that apart from allowing/blocking an app (which other firewalls, even free ones, also do), GlassWire’s firewall has never had a substantial feature added among those requested in recent (and less recent) years.
For example the “Allow once” feature was requested ten years ago and it’s still missing [Feature Request] Allow once
Moreover the firewall feature is for GlassWire Premium subscribers only and leaving it in the current state it’s not the best way to attract new customers, in my opinion.
Also a GlassWire development roadmap would be welcome.
