Like how nextcloud-desktop-dolphin provides Nextcloud Desktop synchronization status, and dolphin-plugins provides git synchronization status, I propose that TagSpaces expose JSON-stored tags in Dolphin’s tagger to allow for seamless management of tags.
As it stands, I don’t see how JSON tags are viable since most people delete and rename files via their preferred file manager (explorer.exe, dolphin, etcetera) rather than TagSpaces, for obvious reasons, and because filename-stored tags are incompatible with software development. This support would allow me to recommend this, however, with ease.
