This is a extremely useful project you have here! I hope you appreciate a little drive-by contribution :)
Appdata:
appstreamcli was unable to parse the XML data, fixed by removing redundant lineshifts
Updated metadata_license (CC0 > CC0-1.0) to comply with SPDX
Added Norwegian Bokmål translation for name, summary and description
Added release/ for recent releases and corrected date of release
Expanded the description and added a few more bulletpoints. This should make the app description validate with appstream-util (Note: appstream-util may still say "style-invalid" for the <p> in the release descriptions being too short)
Added OARS tag (content age rating, required by Flathub)
