Something I recently did:
...
That is the extent of what changes I have done to provinces at the moment; the diagonal line will be taken care of obviously, just felt that the other three ones I did get rid of was enough work for the moment

.
The reasons for those two provinces are to slow down Roman northward expansion, Mutina since the ai seem to dislike conquering isolated inland provinces; hopefully it will slow them down somewhat. Cenomani and the changes with Vindelicias borders are to prevent immediate colonization of Raetia after conquest of Gallia Cisalpina.
Will mainly try to give some (but definately not all) minors more provinces (in those seen in the screenshot I plan to divide Etruria so that the Etruscans will have two provinces). Have some general ideas on what I will try to do in various areas at a minimum and may post them soon, but any suggestions would be welcome as always.
However, you should be aware of that this will not necessarily end up in the next version of this Mod (but it will probably be formally included eventually). There are three things that may cause me to upload a new version:
1. The beta become an official patch, since I will then upload a version compatible with it.
2. I do enough other stuff (like the law stuff, did only a few since the general idea is one thing, ideas of actual implementable laws is another).
3. I have done enough map stuff to feel that it is worth to formally include.
