I decided to submit all the information about the Canary Islands into a whole, to give the creator a better view of the situation of these islands.
These are good suggestions. These are things I was definitely considering during implementation, but ultimately I decided on a 2-province Canary Islands. As interesting as the situation in the islands is in 1444, I think we'd need a bigger map to represent it well. Not impossible at some point in the far distant future.
