The ebook reader on calibre is literally a frame with almost no border. There is nothing to discuss regarding UI/UX. There is nothing extraneous. You can’t even see the frame if you go full screen.
Unintuitive toolbars, takes an unnecessary amount of clicks to simply highlight a sentence, and resizing the window or moving it to a different screen reflows the content unintuitively.
Like everything else in Calibre, it has all the features I want to have and then some, but actually using them is always just a little bit more complicated than it needs to be.
