Hm. Well, I tried setting it to 150, and it certainly makes it more readable
(also, larger!) However, I seem to be running into the problem there that
sometimes an article will be scanned "landscape"-style, in which case I
can't scroll over, and 125 seems to have *both* problems with a lot of the
particular articles in question. Oh well. I'll mess with that some more and
see if I can find one that works.

I'm not sure whether this helped or not, but I'll keep it at one. Thanks!

Interesting. I think I'll stick with the default here, because that's the
kind of display I'm using, but I may try the others later on.

Thanks a lot!
