Change the name of a TileSet

I’ve created a tileset and define the shape.
But now I’d like to change it’s name.
I do not hox to see the properties of the tileset !

With the tileset as the active document, Tileset menu > Tileset Properties. There, you can edit the name.

Ah yes. Thank you !
Are you the mapeditor developer !

That’s a nice tool very usefull. Thank’s !
