I released version 1.1 of ZoomToBelgium for QGIS today. This QGIS plugin creates a button to zoom to any of the Belgian Municipalities or Districts. In this new release districts were added.
Recently this project migrated from Github to GitLab. From now on it can be found on https://gitlab.com/GIS-projects/ZoomToBelgium.
You can download this new version of ZoomToBelgium from within QGIS, because this plugin is available in the official QGIS plugin repository.
