TL;DR/

could e-reader themes also theme the TOC? is it possible to assign a hotkey to swich themes or make Calibre automatically apply the last theme used on each ebook?

/TL;DR
--------------------------------------

I have just started playing with Calibre, I love it, but I cannot find the way to theme the TOC in the e-book reader.

My aim is to have an all black UI with light text over black background for all ebooks.

So I would like to create two themes, one entirely white (the unmodified one is OK) and one entirely black (including TOC, hidden or black TOC scrollbar, and other UI elements like toolbars if possible). Then, make the dark theme default, and when opening an ebook with special css (e.g. code with light background), switch to light theme and use external applications to invert colors.

Ideally, calibre should also automatically apply last theme used on each ebook and assign a hotkey to switch between themes.

I know that I could edit the stylesheet.css for each ebook, but, although I am not an expert, it seems that this is not an easy task because each ebook uses different names for code backgrounds and editing each ebook this way a tedious hit/miss job... Also, for the same reason, a user css style will not suit all ebooks... I might be wrong.
I would like to know what do you think is the best approach to what I want to do. Thanks
