I would like an epub reader to use my account more optimally.
There used to be one on nextcloud called "reader" but that appears to be un-maintained and does not work beyond NC v12.
But recently someone created: https://apps.nextcloud.com/apps/files_ebookreader
Available from the base of https://github.com/futurepress/epub.js/
Could disroot offer this module? Licensing appears to be OK. It would be like offering the pdf-viewer for epubs.
