I started using this editor just 2 days ago, and i already loving it
My workflow is already really fast, and i dont really miss the 2d views (i used Worldcraft for years).
I also love you dont need to work with "weird formats (RMF etc..)", and "Quake Adapter hacks"
There are some things which needs to be added / fixed imo:
- Sometimes the camera movement acts weird and jumps far away from the action.
- texture function "find and replace", this is something i really love in worldcraft.
- fit texture function like in worldcraft (usefull when creating stuff like cargo boxes, windows etc..)
