Feature request: Sort by X + Favourites

[Former user]

My ideal sorting would be Sort By Series, but with the ability to pin Favourites to the top of the list (above Uncategorised, and duplicates, so I can find them in the list if I chose).

Possible implementation could be as a group, like any other Series in the list, or as a toggleable Favourites bar in the master UI.

I hope this has been a clear, concise proposal, but if there's any uncertainty, feel free to email me on [e-mail]
