The UI truly is horrible. I use calibre for converting web pages I want to read offline into epub, but then I use the file manager to transfer the epub onto my device - it seems to be the easiest way. Also, on every single conversion I have to tell it again that I don't want a huge margin. Why would I want to make my e-reader's screen ever smaller? Maybe it's best to build a whole new app out of the low-level libraries and tools that make calibre. A simple app with a simple UI.
