I have discovered that I can get enormously better-looking monospace terminal fonts (Inconsolata, of course) by frobnicating the dots/inch setting in gnome-appearance- properties/fonts/details. My actual monitor is 1920/20.5=93.66 dots/inch, but gnome-terminal and roxterm look best if I set it to 103 dots/inch.
There's only one browser feature that I am certain would notably improve my own life. That would be a mode to restore a session without actually loading the content of all the pages, toasting the network, and demanding passwords all over the place. Just display whatever is cached, and leave the rest of the tabs blank until I ask to refresh them. As it is, I have to "route del default", and then restore, and then "route add default gw 10.0.xx.xx" after the browser settles down. It's a really clunky way to go about things. (If displaying cached content would be tricky, then just leave them all blank.)
