The editor can do a _lot_ of things, but many of the workflows are really non-obvious, underdocumented, and consist of a lot of steps. This "separation of tasks" exists for a reason of course, which is added flexibility (eg. it allows reuse of materials, texture parameters, stats instead of having to redefine them each time; it also allows you to create custom shaders for models, which is pretty great if you know what you're doing), but at the same time it makes common modding tasks like "add my custom chair to the game" so much more difficult than it needs to be.
I have a HUGE list of things to prepare/model so that sounds really scary.
I hope they make a comprehensive and complete wiki or documentation....
