I tend to use the (N)ote function after I explore a tile, to list any resources that I’ve left behind.
It would be useful to be able to tag locations on the map as interesting or worth checking out, in a manner distinct from the current (N)ote function.
I would like to suggest that in addition to the (N)ote function, also add the ability to change the background color of a map tile with an associated note – you’ve basically already implemented it. Certainly, I could just use a color scheme for locations I want to visit, but I suspect the coding for this extra flexibility would be minimal.
Also, it would be nice to have an option to see multiple Quests at once on the map.
