"Horizontal" dropouts are generally not truly horizontal, rather they're
slanted so that they're roughly perpendicular to the seat stays.
With this type of dropouts, it is not generally nessary to mess with the
brake shoes as the wheel is adjusted back and forth for different
sprocket sizes.
There is an unfortunate fad for using old-fashioned rear-opening fork
ends on singlespeed frames. These are _not_ "dropouts" because they
require derailing the chain before you can remove the wheel.
They're a general PITA compared with real dropouts, and it's a shame
that fashion is foisting them on so many people.
They are also, in most cases, installed with the slots level, so if you
use a rear brake you _will_ need to readjust the brake shoes as you move
the wheel back and forth.
The only exception I know of to this is Rivendell's Quickbeam, which has
rear-opening fork ends that _are_ appropriately slanted.
