[Enhancement] More Intuitive EPUB Reader Menu Access

[Daniel Ni]

A little solution for modernizing the EPUB reader's UI could be to have the menu controls that normally pop up when the user right clicks be given the option to popup when the mouse is put at the top 5% or bottom 5% pixels of the screen. 'Given the option' here means that the menu does not forcibly open and remain open as long as the user's mouse is on it as this would lead to cases where the user accidentally puts their mouse in the aforementioned areas and has to deal with the menu. Instead, a menu icon (for example the ☰ symbol) could fade in when the mouse is in those areas, and the cursor could change to the hovering link state to intuitively indicate that the menu exists in the first place and that it can be opened if the user clicks there.

Such a feature can save new users a bit of grief in figuring out how to open the preferences/other desired options while inside a book without having to comb through the Calibre documentation.
