Still no way to view or group by series or collection?

My Nova Pro (original generation, updated to latest firmware) is awesome and NeoReader is a wonderful app, but I always end up having to use 3rd-party readers because there's no way to view, let alone group by series or collection information in NeoReader: I'm surprised this hasn't been added by now, and I'm curious as to whether there's a reason, or is series/collection support at least in the NeoReader roadmap?  Specifically I want to be able to see the series name (eg. "The Locked Tomb Trilogy") and the position in series (eg. "Book 3").  AFAIK 'series' captures the series information in EPUB and 'collection' captures it in EPUB2.
