I use several tags to represent genres and unfortunately, metadata search doesn't find genres for most of my books (from amazon). It can get very tedious entering in several dozen tags for every book...
Anyways, since a series of books will typically have the same genres throughout, it would be great if tags in certain columns would get appended to all books that share a series with the selected book when the plugin is run.
I tried making something with action chains, but just ended up with a headache. If someone has a working chain that does this, please share!
