I see that manual book sorting has been added as a potential feature down the road. That is great.
My question or request would be this:

Allow Marvin to use a search based on a calibre custom column. It allows you sideload books into collections already.

I have calibre setup so that I can define the collection, but it also has a custom metadata field for reading order.

I created this because I read ALOT of Star Wars books. I have them defined by series, but I am also working on breaking them into Eras based on the Star Wars Timeline.

My custom column allows me to define Eras, just like I would a book series, just on a larger scale.

I would like Marvin to read this field and be able to automatically sort my books in the order I have defined.

For most series, just sorting by series works well, but when you are dealing with books across an multiverse with multiple authors, series, etc. it becomes a HUGE headache, especially without an option to manually arrange my collections.

Thanks for your time.
