Currently, isometric tilesets enforce diamond shape boundaries for the map.

Now take a look what tiled actually allows you to scroll: yes, it is a rectangular area. Only a diamond-shaped part of that is actually editable though.

Because some games might not want to obviously show the borders of maps as black pits or whatever, and since screens are rectangular too (aswell as the scrolling area of tiled) - why not allow an option to use rectangular boundaries for isometric maps aswell?

Basically, it would have exactly the tiles in it which you can reach with the edit cursor in tiled currently - so at the sides, every second tile in a row or column is only half on the screen and still editable, while each next one reaches the edge perfectly. That way, it is possible to make perfectly rectangular maps with isometric tiles which are far better for avoiding too obvious and unrealistic map ends.

I guess the tiles would need to be stored in the map export quite differently (rather in horizontal/vertical rows than angular rows that follow the diamond shape as I suppose it is done now), so there would most likely need to be some new sort of switch/property that indicates this which is added to the XML.
