That's basically what we have now. When a grid is desirable (and not installed) you get a warning in the message bar, which you can click to open a dialog which explains the situation and provides a download link, and a button to "install" (copy to the right place) the downloaded file. The only extra steps we could do to improve this would be: - Avoid the "click to download in your browser" link, and instead have a button which downloads in the background of QGIS itself and auto-installs after download - Take it another step further, and just immediately trigger the download task when we first show that warning - Avoid all these issues and download EVERYTHING for EVERYWHERE at first startup ;) Nyall > > Cheers > Martin _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
