Yes, I agree. I like how you have set it up so you can use what you want and leave the rest unassigned.
I have the custom columns, I mentioned, already loaded in Calibre, just be nice to pull it from the ComicInfo since it is already there from when I tagged the comics in ComicTagger. Just saves me from having to manually enter the info again. But I am already blessed with all that you have provided enhancing this plugin so no worries if you decide not to implement. I am super happy already!!
