I am not using the custom sort very often now, but would like to be able to adapt the sort order on the fly to the internet source I am using to find metadata.
Excuse me for being a bit slow here but I wanted to clarify which "sort" you meant - Calibre has several of them
Did you mean the value of the tweak "sort_columns_at_startup"? Allowing you to apply the value there (and possibly other sorts) in your library view after you have altered your sort columns manually?
You mentioned the author sort by in the metadata dialogs. This is something I never touch. Could you explain your workflow and exactly which sorts you find yourself altering?
