Under Settings>Options>Network there are check boxes for, "Allow incoming connections". Either way, even after rebooting, I always see the "RED" incoming connections in the Network graph along with the Out (green) connections.

There is another setting, "Used for reaching peers"; that gives the choices IPv4 | IPv6 | Tor.

I have above "Connect through Socks5 proxy" chosen and the IP and Port filled in, but those 3 boxes are always grayed out and I want to uncheck IPv4 and IPv6 any thoughts.

Finally if you have a favorite tutorial explainer video that goes through these settings in either Core or Knots, much appreciated.

Every now and then I run into a coin I've never heard of, usually because it's suddenly doing a lot of volume or someone mentions it in a group chat. I want to get a quick read on it: what does it actually do, is anything unusual happening right now, that kind of thing.
What do you guys do in that situation? Do you check a few sites separately, use some tool, or just not bother with coins you don't know because it takes too long to figure out? And roughly how long does that usually take you.
