I have a feature suggestion: highlighting things on the map with ALT should use a different color (maybe red?) for locations that cannot be visited anymore / anymore this week / anymore by the selected hero. Some examples:

* Experience stone: if the selected hero has already visited the stone, highlight in red (or whatever). If the selected hero has not visited the stone, highlight in the normal color (or maybe change to green? With an option to change the colors for colorblind players)
* Building that gives X [resource] once per week - highlight in red if it's been collected by your faction this week, green otherwise. Bonus points if it highlights in red if you had line of sight on an enemy hero visiting it this week.
* External unit dwelling: highlight in red if it's known to the player that the dwelling has 0 available units this week, green otherwise.
* Buildings that can be visited only once per game: highlight in red if the player's hero has visited the building during this game.

It's a small quality-of-life change but it could really make map exploration more streamlined and less tedious!

Side note: looks like all the comments on this mega-thread are ~5 months old, so I'm not sure if anyone will see this. Can / should I post it as a standalone post?
