I agree with you.
I've been writing and selling software for well over 25 years now, and my philosophy is to present the user with the info they need and leave the flashy icons and other cr*p to marketing exercises masquerading as applications.
I wrote a rant about mp3 players on the download page for my yPlay2 software, maybe 15 years ago, complaining about computer software that was designed to look like the device it was 'replacing' - e.g. an MP3 player with fiddly little buttons and a pretty skin, instead of clearly labelled buttons and a regular Windows or Mac UI.
Sure, they look cool, but usability goes out the window.
I can't even see the new Author Central page yet, but the old one was bad enough with its list of a whole 5 books at a time. (my stuff takes up 11 pages) Worse, they group all the different editions and only show figures for the highest-ranked, so I'll see an audiobook instead of the ebook for 6 or 7 titles.
What's wrong with listing 50-100 books at a time in a nice clean spreadsheet view, downloadable as CSV, with links if people want to view the charts? A list you can re-sort by clicking the headers. A field showing the date of the most recent review, and a total review count, and an average rating, and the current sales rank. The data is there, after all.
So much possibility, but they don't ask authors and publishers what they want.
