If a document has more than one tag (ie, “writing” and “template”) it’ll appear in the document list for every one of those tags. This is intended function, and the thing I’m asking for is the ability to hide documents with certain tags in displays of other document lists.
For example, if you look at the document list for files with the tag “writing”, and have chosen to hide the “template” tag, documents with just the “writing” tag would appear, but documents with both “writing” and “template” wouldn’t appear, since the “template” tag is marked as hidden.
