Hi Dalton,
I was wondering if you could somehow indicate WHICH long comments column is being deleted since there is no way to tell by the cursor (at least in my settings that I haven't figured out how to change) which column I am indicating. It's just one long highlighted row and I am hoping that when I highlight my entire library (since you cant just highlight a column) that the cursor is in the desired column. Otherwise, love the plugin!
EDIT: changed Calibre to Calibre Settings and not System Settings because system settings made the row cursor opaque and I couldn't see the individual box. No need for the changes
