We have "Fort Level" map mode that shows forts and ZoC provinces, however up-to-date rules of movement in ZoC are undocumented. As rules are very complex and can change between versions, I suggest following solution.
- There should be map mode that colors provinces depending on their accessibility for certain army:
- red - provinces that are inaccessible by land (i.e. use of transport ships is not considered);
- yellow - provinces that are accessible by land, but allowed path differs from shortest one (in other words, automatic path would be different if army was black-flagged);
- green - all other provinces.
- For performance reasons area where provinces are colored may be limited, in this case provinces which are farther than threshold are painted with grey color.
- Click on any army (including enemies and neutrals) should change viewpoint to theirs, similarly to how other map modes work (e.g. "Diplomatic").
