Add subpiles or a Tag feature to group similar comics
I know the piles were originally created to mimic your collection as far as what comics are in what "box". So Box A, Box B, etc. I like that but I also like grouping every Spider-Man comic I have in a pile so I can quickly see every title at once. Since my collection is split over many boxes I don't think there's a way I can currently do this unless I make a pile devoted to "Spider-Man", which is what I'm currently doing.
It would be nice to either do one of the following:
Subpiles: I could create a pile "Spider-Man". Then inside there, "Box A, Box B, etc.". This way I can still group by character but within that also see where each one resides.
Tag column: Add a column where you can give the comic a tag that you can use to run a query on later. So I could tag any comic I want with "Spider-Man", then run a report "Show all 'spider-man' comics I own". This feature probably has other benefits I haven't thought of yet. Maybe you want to keep track of comics you have gotten from a certain vendor or person or whatever. This way you can run a report to view them easily.
