Hi all
I've been using Calibre & plugins for years (thank you all for such awesome software: a game-changer

), but my technical knowledge is non-existent at best so my way-to-go, when I want to try and implement new things, is to check here if someone had the same idea and shamelessly copy and paste the configuration
But since I can't find anything this time around, I'll try the direct approach of simply asking my question(s). If I missed the obvious, please link me to it
1) I know in Calibre you can enable the "show average rating" in the tag browser, but would it be possible to have the average rating (by author) also as a custom column?
If yes, can someone help me to set up such a column?
2) The standard rating column doesn't accept half stars, so I created a custom column of Rating Type that allows half stars. Is there a way to show the average rating (in the tag browser and/or as a custom column) based on this "Custom Rating" column instead of the standard one?
