There’s been a lot of talk regarding better handling of box sets. I’d just like to add ‘series’ to this theme as well.
For example, there are many CDs that are released separately as a series though are not necessarily part of any boxed set. It would be good for Roon to allow the user to group these together as a series, in a simlar way to the box sets. So when browsing in album mode or on the artists’ page, the series (or box set) would appear as one item - which when clicked, shows all the albums or individual items in that series (or box set).
