Description Guilherme de Almeida Suckevicz 2021-03-11 17:17:15 UTC

Discover fetches the description and related texts of some applications/plugins from store.kde.org. That text is displayed to the user, after turning into a clickable link any part of the text that looks like a link. This is done for any kind of link, be it smb:// nfs:// etc. when in fact it only makes sense for http/https links.
