I understand what you're saying but it doesn't apply universally. Different people have different way of dealing with things. I prefer the exact opposite of what you said. Besides, with popups I would actually have to spend less time researching except the very first time after installing the Firewall which is obvious. After that I wouldn't require to check the logs because I already know nothing else except what I allowed tried to connect without my knowledge. With popups I would immediately know if something unexpected tries to connect to internet and take required actions while without popups I wouldn't know that at the time of happening, something may break in the background without me knowing because I wouldn't be checking the log all the time. Few days ago I noticed after installing a security program "Wisevector", at first run for some unknown reason "lsass.exe" tries to connect online. I immediately reported it to them and asked what's going on.
So anyway, there's no right or wrong here. It's just matter of preference and I prefer to be notified without any delay
I agree with this and much prefer pop-ups. The initial setup is may be annoying (it would be nice if firewalls included a "well known" applications list that would have the rules created for it automatically, like Outpost Firewall did. Of course, it should be up to the user if they want to do it automatically.), after that you have complete control of what is going on and if something new tries to connect you'll know immediately.
With the non-pop up method, as SerioiusHoax, you will eventually have to do research, a lot of it! Because if something breaks, then you don't know why it's being broken and not working and then you have to go through the list of applications and try to figure out what service or application is being blocked and what you need to unblock.
I like SimpleWall personally. I've compared it to Windows 10 Firewall Control and prefer SimpleWall, the UI looks like standard Windows (W10FC looks like old Windows), you get better separation of applications, services, Windows 10 Modern applications. One thing I liked about W10FC is the "allow once" button on pop-ups, but SimpleWall has "allow for x amount of time" which I thing substitutes "allow once" just fine.
SimpleWall requires disabling of Windows Firewall, which I personally like. I don't want an application that managed another running application. Just have one. If it registered as an "official" firewall so the warnings would go away, it'd be great.
Finally, SimpleWall is available as a portable application, which I really like!
The only pet peeve I have with SimpleWall is, why is "simplewall" name, not capitalized and properly cased.
