I use RMSO SMSO variables for ${PS2} ${PS3} ${PS4} and numerous shell scripts
& make files.  Setting these variables eliminates 2 calls to tput every time
I want something in Stand-out mode.

For prompts I normally use "${SMSO}[${SYSNAME} ${LOGNAME}]${RMSO} " with the
current directory shown on the status line or window label area.  PS[234] are
variations of PS1.  When executing vi, the status line/label changes to:
"${PWD} VI ${*}", upon returning from vi, the current directory is then
redisplayed on the status line/label.  Similar manipulations are done when
executing rlogin, telnet, ftp or su.  It makes it a lot easier to deal with
multiple windows on several terminals.
