Allow more fields to be presented/sorted in "Middle Pane"
I need to do some extended data maintenance for my library, which would be greatly facilitated by presenting/sorting the middle pane database column(s) not in the default list (e.g., "URL," "Archive," "Loc. in Archive"). Is there a way for me to temporarily add column(s) to the middle pane of the database entry/edit window?
Is it difficult to make a little pop-up that lets you choose which fields you want to display and then ultimately sort by? This would be the ultimate solution.
