Map sizes when loading a map

[bbbmmmlll]

Should the map size adjust to the size of the loaded map? For example. if you load a map that is 40x40 and the current map is 25x25 you lose everything over 25 rows or columns.

That means I need to know my map dimensions and resize the current editor map before I load a map from an external file. That is tedious.

This one is on the shortlist too.
