As mentioned, the webdav support is already there. Regarding the group support, currently there is no concept of groups in cubby at all, so I will mark this as solved for the moment as there is no intention to add some kind of group system so far.
@BrutalBirdie hm not exactly sure why the plugin would remove the URL bits and also no clue how to work around this. The app listens on hashchange, which is probably why it keeps refreshing. Maybe the plugin wrongly detects things as tracking?
@nebulon I am not a programmer/developer so I am unfortunately not in a position to contribute to the code. However I am more than happy to help with testing as well as sponsor the development of new features! 🙂
With regards to the subject of this thread, it seems that one option for OCR would be to use OCRmyPDF and a search engine such as Solr or Elasticsearch.
