I have updated to the latest version of Photo Mechanic and can see how useful the ability to turn lists on and off inside Code Replacement. This got me thinking about how amazing this would be if it could be extended to Autocomplete where you could leave a few lists loaded and use a drop down or a check box to make the one that you need active. This would be better than having to load/unload lists every time you wanted a different one. It wouldn't be revolutionary but it would be extremely helpful.
I'm sure that there are technical reasons why you cannot access multiple autocomplete lists at the same time but if those could be overcome then that would be equally useful.
