I'm sure calibre 2.0 is a great technical feat, and kudos for all the work put into this product, but judging by the screenshot the user interface is equally clunky as in 1.0. This software does mostly everything I need it for to convert ebooks... but can you, the authors, please improve the UI?
Considering that it's free and open source, and that I use Calibre for a fraction of a percent of the time that I do actually reading the books on my Kindle that I loaded using Calibre, I would rather that the creator of Calibre focused on the technical details, such as making sure that the file conversion/transmission is working correctly.
I don't think this is a matter of calibre de-prioritizing fixing the UI. I'm pretty sure it's a conscious choice. They know their UI backward and forward and it works for them, therefore anyone who complains about the UI Just Doesn't Get It. That unicycle is BEAUTIFUL, dammit.
