D as distributed is designed to use dim video highlighting. If your TCAP uses reverse video highlighting the display will not look right until you use ZCNFG and answer yes to the reverse video option. If you use CP/M Plus and you would like D to look for and display CP/M Plus disk labels, instead of ZCPR3 named directories, then answer yes to the disk label option. Because of these configuration options, distributing four separate versions of D is no longer necessary.
