The Pro version of the plugin allows you to combine different maps, so you could have maps of countries divided by regions combined with their neighbouring countries. In this example we create a map of both Portugal and Spain and combine it in a single map, using the overlay feature.
In this particular example, since both countries have islands that are far from the mainland, the map seems a bit zoomed out. If you only need to display the mainland regions, you could setup a different initial zoom.
Using Custom Maps
The plugin allows you to use custom geoJSON files to create your maps. I have created a custom map for the Iberian Peninsula map using QGIS software and moved the islands closer to the mainland and merged both maps together. I hosted the source file on github so anyone case use them. This is the resulting map below.
This representation of the map has the advantage of having the islands closer and therefore the viewport for map doesn’t make the mainland portion so zoomed out. The disadvantage is that the coordinates for the locations of the islands are not the correct ones and therefore you would need to use different coordinates if you need to add markers.

If you’re using the plugin to create maps for individual countries with data about the new coronavirus (COVID-19), here are some tips on how to do it.
Portugal confirmed cases by municipalities

Data only represents ~50% of total confirmed cases.
Getting the data
The data available might not be formatted the way you want. If you’re displaying a small country with a small number of regions, you can add the data manually to each region. In the example above for Portugal, the data is released in a table in PDF format, so it’s not available to be used directly by the plugin. I first needed to convert that data into JSON and then use it as a custom data source for the map. Consider the id property of your JSON entries, should match either the real region ID or the name. The plugin won’t be able to recognize entries that don’t match either.
Creating the Map
Once you know where you’ll get the data from and have selected the map, you can create it. Here are some links that will help:

It’s always interesting to see how the maps change throughout history, they are one of the most powerful visual ways to see historic information. Below is an example of a map for the Roman Empire, which lasted a few centuries and included large territorial holdings around the Mediterranean Sea in Europe, North Africa and West Asia.
The plugin itself doesn’t include a map of Roman Empire regions, but since we can use custom geoJson files, after some online search I came across a map for it which I then adapted to use with the plugin, also using the overlay option to display it in the normal world map focused on the Mediterranean sea.
