				Noticed a "what's new" item you guys are working on..
			 
			
			"When updating an OPF, remove custom columns from the target that don't exitst in the source" Any chance you can fix that so it's an OPTION? I don't know how many times having the opf files not being changed has saved me from mistakes in deleting columns that I regret. |

			Sorry but the whole point of the OPF files are that they are supposed to be an accurate reflection of the current book data/state of db, not a means fo recovering from mistakes. For that, use backups.
