OK. I'm in the midst of setting all my Genre info in a new custom column so I can get the Collections I want on my Kindle, when I realize that Calibre2opds doesn't utilize custom cols, only tags.
And, IIRC, it does all my tags, not letting me exclude stuff.
I like Calibre2opds' generation of static HTML that I can serve with any http server (& dropbox!), rather than calibre's server. Are there other alternatives that can use custom columns?
@meme, want to generate some HTML, too?
It'd be great if these two features were driven by the same meta-data.
