Basically, split the existing general categories into more specific categories:
- Map: yields, grid, resource tags
- Game: load, save, options, retire
- Camera: rotate, zoom, fly-mode
I highly recommend that this be done *before* translating as it is difficult to reorganize translated text unless you speak that language.
This involves only XML work -- no coding. I can easily explain how to create more categories and would love to see someone take this on. :)
