Sergeant at Arms
The city/castle/village icons replace the dots and are fully functioning with mouseovers, checkboxes etc. The color overlay is something I'm still fine-tuning as it's a balance between being clear enough to read properly, yet not so bright as to look wrong, or clash with the icons.
I did use the Map Poster as a guide on where to put Mountains, but indeed my map is not quite as elegant, code-wise, as the original, in that the paintover needs re-tuning if you change the terrain.
I don't see that as a real problem, as I am not changing the terrain for my mod, and even if I was, it was simply a matter of waiting until the new terrain was done, and modifying the paintover. It's an awesome piece of coding by rubik though, and the code I use for mine is still 98% his, just a few simple changes on my part.
More opaque overlays, step 1:
I like step 2 best, for a balance between colors and overall look.
