Maybe some plugins could partly do it for some certian file types, for example, the "wdx-NTFS_diz", the "wdx-jpg-comment", but it's so slow when searching. Maybe the plugin "Virtual Panel" could also partly do it, however, it can't track the file changes(renaming, moving, deleting, etc.) and the "files" in VP is virtual(some operation for real file couldn't be performed). Maybe description could partly do it, but the searching speed is so slow that we can't to find a file by the description.
In fact, one file can have many tags. One book→read or unread; the author; the content:history/love/...;even the name of leading character...Pictures;Songs;Almost all type of files, the situation is the same.
I think TC should ++.
Here is a tag tool for reference:
