Maybe it’s just my preference. I’m not doubting DMs out forth the bulk of the effort or anything, and I’m thankful for all who have served. (I say that tongue in cheek but not sarcastically lol, it is a big commitment.) But I think the Lazy DM approach is better and I also really enjoy collaborating about lore.
I don’t think you should disable self signed warnings. It would be better to import those than disabling the warning as it is a very important warning.
As for disabling https only mode for certain URLs, I don’t know, and it would be a useful feature. Some of my corporate stuff oddly redirects to HTTPS but just gives a blank screen rather than a connection refused or something. Not sure what it is. Probably something is misconfigured somewhere but it’s not something in my control. I didn’t have time to really inspect it so I just disabled the https only mode for my work laptop.
