Hey!
Older post but I'm still replying.
I'm with you. An option to stop seasonal map change would be great. Also don't like the look of unupdated chunks. Maybe just two options like "seasonal change" and "all-summer" or so.
For the roads: I already thought of something like painting on maps. Nothing fancy. Maybe just pixel by pixel. So you could mark things yourself, not just like roads but also circles of e.g. "dangerous" areas or so. I would like paths/roads also to be more visible on map but the problem with automatically rendered paths will be to find a colour to be visible on all surfaces. Maybe full white or black. Red or yellow are not fitting. Those colours are more fitting to borders and such besides. Still, I would find it quite immersion breaking to have roads rendered in bright colours whereas buildings and such would just be rendered as of now. I like to see my village/town rendered on the map. A solid bright red/white/black/... line between houses would infuriate me :D. So I think a painting-option added next to the existing markes would be a solution for everyone.
