Now, the real question is whether or not Kovid Goyal (the maintainer) releases his iron grip on development. For years, seemingly any bugs are features, EVERY TIME. Good luck getting a commit accepted! You'll probably get an incredibly passive aggressive reply about why he doesn't see a need for it, no matter how obvious and simple to execute.

Can we get a real UI, autoupdates (and without needing to download the whole giant binary every time), a database that doesn't choke on realistically large libraries? How shaving some time off of the 45 seconds the application takes make an Amazon API call to grab metadata and a tiny cover image? These are just the obvious, major issues that have been present for years now.

Calibre is already that half-assed community project cliche. One that has so much potential at first, but falls apart since no one can see the forest among the trees. Has been for a while now.
