The chalkboard is great after 8 pints... helps keep me straight. Its usefulness diminishes with each successive pint, though, as my ability to read deteriorates.
Taps are 4" apart - I already marked the spots where I can comfortably fit 1 more on each end for a total of 6 taps (if I ever get there - who knows! A lesser man may say that 4 beers is enough.)
My driptray is bigger than yours.
