Feature request: tag hierarchy
Being able to do a hierarchy tree of tags would be very useful. For instance, instead of having to add both a tag for 'reading' and then 'reading – in class', I could add the 'in class' tag, which is a "subtag" of 'reading'.

(Incidentally, it would be nice to be able to remove one's own threads from this forum, but that's really off topic here.)
you can try the "nested tag" feature in Zotero-style add-on

Still, It would be better to have hierarchical or nested tags built in zotero itself for easier management and being more future proof compared to lack of plug-ins updates in some cases.
