I really like the DTI tools. I have not come across any "empty" FA voxels with this method, which I think is related to nonlinear estimation of eigenvalues. This is an improvement over the linear estimation method.

I am really interested in the weighting factor, as you note that it could be used for QC. I haven't had a chance to fully dive into this yet, though.

The output of the individual tensor components is very helpful since I export these to a second program for fiber mapping.

The automask feature works very well for the most part. There have been minor issues in areas with high suscept. artifact, but this is related to issues outside the realm of the current program.

If additional features are to be considered, it might be nice to have trace automatically calculated, which is simple to do (bucket #19, perhaps!).

Also, integrated 12 parameter affine (or other relevant method) ecc would be a nice future addition.

That is all I can think of right now. All in all, I have nothing but positive feedback.
