Totally agree. It's always been on my radar to add these features, but as always it's finding the time.

hmm. Perhaps I'll only do the tileset switching one then;)

well don't hold back waiting for me - you know how long that could take!

If I happen to get the tileset switching running fully, it probably wouldn't be long off for me to get the rest all together anyways!(now that I've looked at it a bit) I think most of the code for the switching would be exactly the same as for opening new maps.
