Just a remark here, having read the direction of one or two threads: though it may be tempting to plan things under the assumption that you can cram in a few more provinces into your favourite area, it will be an awful lot easier if we DON'T edit the underlying map for the time being. For one thing, it's a huge amount of work, especially anything which adds new provinces in Europe. More importantly, it'll probably make the mod non-Mac-compatible, which would make me unhappy, given I'm a Mac user.
