As a warm up for the release of EU IV I have been returning to EU 3 DW the last couple of weeks. I have created a large empire out of Scandinavia with lots of oversea colonies, as well as substantial land gains in continental Europe. To make it easier for me I would like to have the option in EU4 to create new vassal states out of my colonies and not just recreating older no longer existing nations with borders fixed by history. Using an interface like the one we have in EU3 when making a peace offer would be very handy creating new nations with control over exactly what you are giving away and also what they are supposed to be called.
