The mapmodes interface, which was already greatly improved in 1.14, has received another upgrade. Instead of each of the 10 primary mapmode mode slots only holding a single mapmode, you are now able to store multiple mapmodes in each slot, and switch quickly between them by pressing that mapmode button or its associated hotkey. For example, you can store the regions, areas, colonial regions and trade companies mapmodes in a single slot and quickly switch between them, depending on which particular one you are interested in at the moment.
