Calibre, at its heart, is a spreadsheet. I don't believe there is a better format than that used. The internet abounds with "elegant" web pages that seek to provide adequate white space, as an example. They are beautiful and horrible. You are paging all over the place to get the info that's marooned in a white space desert. Data and density are bed-partners. The fact that an elegant UI flows from point to point lacks meaning. On spreadsheets, eyes dart to learned positions.

Kovid's work is elegant. It promotes the basic need. It enhances that with useful panes. It has greater user controls. It is expandable like few other programs. Any programmer being honest will envy the design and execution.

As Mies said, "Form follows function."
