Including cells, and/or most importantly cell categories for roads.

I do not know about the technicalities, but it would be pretty useful to have the cell data included in the exportable geojson files as attributes.

For example, every road has a cell id so in qgis it can be recolored maybe. (like in draw roads by cell)

The "Export" button in the UI makes a GeoJSON file that only includes things relevant to the savefile; it's not meant as a general export for rendering elsewhere. We can export everything shown in the app, including cell IDs, but I'm curious what the goal of using the data in QGIS is. Is the purpose to produce nicer static images, like #423? Do you have other ideas for styling / displaying anything that we could try implementing directly in the tool instead?
