I’m not sure if you are suggesting a setting that sets the default level of detail for the Firewall so elementary users see a simple view and experienced users always see more detail. If you are then I don’t think that anyone has suggested this which deserves a big 
. This would be a really useful setting even if it is only for all applications. Many users would only ever use the simplest view which could be much like the different views of Windows Firewall versus Windows Firewall with Advanced Security.
There are lots of suggestions for more detail and greater control over, for example, hosts and IP addresses
I’d much prefer a different solution for the problem of too many apps to see them all in one screen.
All applications should appear in the same tab whether they are blocked or not. They can then be sorted and filtered in various ways. We would not be able to do this in separate tabs.
For example, I should be able to see all processes from the same publisher, such as all the software Apple iTunes installs that have network connections rather than having them separated into two different tabs based on their blocking.
