#2 Folders for models in Editor

[Yill]

The increase of models will quickly lead to a rather large heap of models. Selecting/finding them in the model editor of the TR editor is getting harder and harder. Perhaps some selectable folders might solve this

here's a couple folders I'd like to see:

Vegetation
General scenery
Miscelanous objects
Wilderness buildings
Morgendil
Vaern
...all other city names

Coolest would be if one could add folders to the editor himself.
