Hello!
My suggestion is this: the ability to change the ground without duplicating it/making another one.
A button saying "Convert ground". When you click on it, a little tab appears, with the names of different grounds. If you click on one of them, like, "Stone", the ground will automatically become a stone ground, but with the same properties of the old one.



And then...



Voilà!

And sorry for my bad editing skills.

This is neccesary, though there are software to do this :D

I don't know about others, but I don't see myself needing to do this very often, out of all of the maps I make. You could always just edit the T="" value for the ground in the XML, but again I don't think it's that common to deserve a button itself.

like shamouse said but i think map editor should be changed for new map makers not having everything in xml and being so confusing so support

Oh yeah, I know what you're saying. Support.

You could easily just change the H and the L (Height and the Length) to the same size as the other floor, but this sounds much quicker.

all you gotta do is get xml code post it somewhere but if in forums dont send it! and change L"groundnumberyouwanthere" its simple but if you peeps are lazy then

I would find this useful, but it doesn't need a button of it's own. Why not make the "Wood ground" title a link for example, allowing you to convert the ground into something else. The editor has plenty of silly buttons already x)

personally it'd just clutter up the editor more, and it's not that hard to grab xml and change T= tags.
