Hi, thanks for all the responses!
As for the one-off use, I just wanted to know the ballpark for a single book to compare it to another - and I assume that's not the most common use case, so I understand the confusion
but that is what I wanted to do
I had previously no idea custom columns even existed, and I actually tried around to add one but couldn't make it show up in the preferences dialog since frankly, I just have no good clue on how they even work. I know most users would want to permanently set up one, but it'd be nice if for a one-off check that wouldn't be necessary
I also had no idea the book editor existed, I'm really not that much of a power user. I get how the plugin works makes sense for power users, it's just a little confusing for beginners right now. Being able to see the info without being required to set up a custom column to display it permanently would help with that
One additional place I checked was the book metadata/detail info dialog but I couldn't see it there, maybe it'd be possible to add the info there as well? Just to make it a little easier to find for folks who didn't configure a custom column and aren't looking to do so
