I have used both the NWN 1 & 2 toolsets well. This new game and toolset look very promising!

But besides from little information about scripting and story/conversation editing, there are some other important basic issues in the Divinity Toolset which come to my mind while fiddling around with it:

1. Lack of easy editing of creature statistics, abilities, etc.
2. Lack of easy editing of items, objects, etc.
3. Lack of easy editing of player abilities, spells, and other essential game mechanics.

I know it is possible to unpack files and changing at least some of the things above, but at least in regard to point nr. 1 we need to be able to handle this quickly and easily from within the editor. Anything else would be very time consuming and unpractical.
