Thanks for your kind words about AFNI. I designed the AFNI package (if you can call my semi-random process "design") to be flexible and allow for lots of different usages. For a user who wants/needs this diversity, and is willing to learn what it takes to use it -- a coding point of view, sort of -- AFNI is pretty useful.

Re-doing the GUI is a lot more work than you might think. I developed it, starting in 1994, with no clear vision in mind. Over the years, a lot of features have been glommed into it. To do it over would require a top-down series of decisions about what features are useful -- all the features were added for some reason, so ejecting one means that someone somewhere loses something. Then it would require designing the look/feel of the new interface, and then programming it afresh. It took me 2+ months to get the first version of the GUI to do something useful, and I am (or was then) an extremely fast and capable programmer. I figure that *if* I could find someone good to work on it, then at least a year would go by before it was reasonably capable (by my standards). I personally cannot stomach doing that kind of work anymore.
