Yeah I should probably look into it more. Can Comodo's firewall be used standalone, i.e. without its antivirus? What I needed from Glasswire was click-to-allow on each network access, I couldn't find that in any product I tried a few years ago before I decided on Glasswire.

Yep, just pick the firewall from the installers and make sure you uncheck everything except the firewall during the install (they are tricky, these guys):
after installing go through and (again) disable everything but the firewall. I also use their firewall to block their firewall (hah) from updating. Once you do this it works fine as a standalone firewall and the only reason to ever update it is if you reinstall or upgrade Windows.
EDIT: It does per-app blocking great; that's why I use it. I tried glasswire and didn't like it (or maybe they wanted to charge me money, I forget).
I am a bit confused about Portmaster and Safing. The documentation on Safing constantly refers to Portmaster. Does portmaster do anything besides act as a local firewall?
