And on the note of calibre being hideous -- I wouldn't go that far

(although I am no expert)... but there is no doubt that aesthetics is a distant consideration. I am pretty sure no specialist graphics designers have ever touched the code, though.
I too am of the opinion that aesthetics can take a running jump, and the intuitive functionality is a priority.
But if someone were ever to take the job of renovating said aesthetics, I wouldn't protest. I'm not holding my breath -- several people have popped into the forums with *ideas*, were told "patches are welcome", and never came back.
Interesting how many people leapt to take offense at the description, though.
