I think by far the most important little addition to be had is the ability to generate battle_models.modelDB from XML files. Those XML files don't exist, and there's no tool to generate the modelDB file from them. I suppose hypothetically we could create all our own XML files for our units and attachment sets, and then create our own parser, but if CA released the tool they already created, along with the XML files for vanilla models, it would help immensely. It would be nice if the game itself generated the modeldb file whenever that file wasn't found (same as with .rwm), but if that's out of the question, then a tool generating the file from XMLs would be nice. It's far better than editing the modeldb file by hand. See
this thread about how CA themselves generated the modelDB file. I'll go ahead and give this a (9) or even a (10) in desirability...
