I request an option for directly reading a OXC(E) terrain .rul file in MapView.
Instead of having to use the RulesetConverter initally and re-convert whenever something in the .rul file changes.
hiya, good idea,
unfortunately my flagging health is putting me behind on a bunch of stuff (already) ...
imo, Mapview should get a means of loading (user choice) "MapTilesets" -- if that were done, it'd be a good time to also put in loading a Terrain.rul file. One thing that strikes me right away is disabling a bunch of maptree stuff (so a maptree that's based on a .rul file can't be changed, as you note).
automagically changing the Mapview (global) Basepath is also something to consider (though this can already be done with the Configurator it would be a nice feature, which however necessitates a mechanism to automagically change it back ...) etc.
Personally im glad that Mv2 seems to be stable in its current state, but (for me) this would be a fairly big new feature to implement,
