Hi!
Just to say that I added a simple visualization in the MOEasel to keep track of the 'as yet unclassified' method category. You can open an OB by right clicking on a red node. Fixing it and pressing 'Generate' again to see your progress. Nothing revolutionary, but I find it useful in my case.
Note that are they other useful visualizations for example 'Abstract classes' that check no abstract classes is a leaf.
Version 2.40 of Mondrian does not have any 'as yet unclassified' and abstract class leaf
Cheers, Alexandre
