When using maps found online and having to apply dynamic lighting; it is quite a pain sometimes if a rectangular room has several entrances as (at current) each wall and door needs adding individually. Even worse, round rooms have no way to remove part of walls. Suggestion: A dynamic lighting erase button/function. This would also be rather handy as (for example) being able to remove ad-hoc pieces of walls etc. as characters perhaps try to blow holes through things.
