Hi Bjørn, thanks for the very detailed answer - I really appreciate it.
It nice that you can use “Typed Tiles” but in my case I first need to apply these “sets of properties” when I have added a tile to the “Objects Layer”.
And right now it works totally as I wished for - but the selection / set tile thing is a bit confusing …
I think the difference, which created the confusion is that when you add tiles on the “Tiles” layer, when you move the pointer around the grid, the current selected tile is visible - so you kinda know if you click, that particular tile will be set - but when you work on the “Objects” layer, even though in “tile mode” you just see the pointer - which is more accepted as a “selection or click” pointer, that a “lets drop a tile here” thing 
Where do I find the latest snapshots ? On the downloads page, the snapshot looks older than the released 1.1.3 version ?
