I agree the app is good - but the user interface has always needed simplifying.

Do you mean you simplify the UI yourself with the configuration settings or that you wished it was simplified ?

I found calibre less clunky and very clean once I hid icons, menus and submenus I don't use.

Maybe there should be some kind of toggle mode (easy, god, expert, etc.).

More specificity on what you'd like simplified would be useful.
