More zoom steps?
Epiphany's page zoom, using the buttons or keyboard shortcuts, jumps up from 100% to 125% to 150%, and similarly down to 75% to 50%.
Firefox's steps are 100 → 110 → 125 → 133 → 150%
Chrome: 100 → 110 → 125 → 150%
Safari: 100 → 115 → 125 → 150%
I often find sites' fonts just a little bit too small (or big), so I miss the 110% (and 90%) step. (And as a longtime Firefox user, the 133%, but not nearly as much.)
