My app can switch themes dynamically, and having to swap text color to white on dark themes and black on light themes is a lil' bit of a bother. IMHO it should exist as an override to the default style settings, and by default, the HTML view should adjust colours accordingly to the theme applied (maybe even hyperlinks being in the accent colour instead of blue..?)

That is, of course, if it's at all possible. I admit, I don;t know how it runs behind the scenes.
