Title: [#817] Add two sets of breakpoint variables instead of just one

Option takes in a dimension in em or px. By default we go off 3x the
sidebar width to switch to medium mode (one-column vs multiple columns),
and 4x the sidebar width to switch to large mode (keeps the multiple
columns; whitespace difference mostly)
