OK, but I've never seen in any cave symbol list "presumed wall probably formed by blocks" :))), but I've seen many times "presumed wall" or something simmilar - so I think wall-presumed will be enought. And in any case - for each combination of type/subtype - you need a separate symbol. Therefore I think we need only types... Another point - wall-invisible or wall -subtype invisible is completely not realistic. Therefore it should be probably renamed to outline or something like this... > Theother thing to consider is the interface.
