Change page background colour of a PDF when opened in Chrome.

[spazmodic]

Hi. Firstly, thank you for an amazing and very useful app . I would like to make a feature request (or ask how to use a feature , if this already exists ).

If I am reading a PDF using chrome browser as the reader, I would like to know how to change the page colour, behind the text. Is this currently possible, and if not, is it a feature you might consider implementing?

(I don't mean the side-bar colours , outside of the PDF viewing area : I mean the colour of the page, directly behind the text).

Thanks again !
