I released version 1.2 of ZoomToBelgium for QGIS today. This QGIS plugin creates a button to zoom to any of the Belgian Provinces, Municipalities or Districts. In this new release provinces were added.
This project can be found on GitLab: https://gitlab.com/GIS-projects/ZoomToBelgium.
You can install this new version of ZoomToBelgium from within QGIS, because this plugin is available in the official QGIS plugin repository.
