Templates for GSC.

I've heard several times about custom templates for the random map generator, which are said to be much better than the default ones, and playing with them is significantly more interesting. I haven't specifically searched for them, but I checked a couple of familiar websites and didn't find anything related to them. However, the desire to use them hasn't disappeared, so I'm asking everyone who can share these templates, instructions on how to install them, and also useful mods for the editor (like a mod for a well) to post them here (or links to resources where they can be downloaded). I think I'm not the only one interested in them, and some people might not even know about their existence, but it's really a useful thing; the default templates are just not good enough without mods. Thank you in advance for your help. P.S. For those who don't know, GSC stands for random map generator.
