Yes! I use it!

For mobile, it's really nice to have, as I find the "Normal" setting much too large (I like tiny fonts). On desktop, I use it, but I suppose I could easily whip up a CSS stylesheet to tweak it.

I like it the way it is, and I highly recommend that people set up multiple profiles if desired.

Here's what my DDG looks like on desktop:

Thanks again for the excellent customizability!
