You may have answered my only concern of moving on to v2.x of this great program, as new version did not appear to have a way to import custom map data, now that the maps are stored in the database.

What was missing was a method of putting these custom maps in into the new database structure. Renaming the tiles is a pain. I have some maps from 1895 of my home town that I need to try this with.

Thank you this appears to be the missing part of the puzzle.
