Looking for a way to manage digital comics

So I am drowning in comics in CBZ format (legit; purchased mostly from Humble Bundles). I would really like a way to manage them. All my epubs end up in Calibre. I know Calibre handles comics as well as books, but it doesn’t feel like the right tool. Does anyone have anything like Calibre, but specifically for comics? I’m willing to pay for the right solution. Doesn’t even need to be able to push stuff to my tablet.

(Oh, and is there a good comic book reader for Android that I can install on a Fire tablet?)
