So, thus far I have added groupings, aggregates and degenerate dimensions to the core, and I have added references to JxBrowser which added 200MB to the project. :(
The UI for the data explorer is challenging. I don't want to spend the rest of my life on it but I also don't want to produce an ugly piece of crap reminiscent of old Linux Motif/Tcl/Tk apps. The Java UI is much more limiting than I remembered - most new gestures aren't accounted for, even in the newest stuff. Maybe JavaFX?
