I find the default terminal layout a bit hard to read between where the previous command ran and ended its output. Adding this line to your .bashrc file puts a horizontal line before each primary prompt making it a lot more readable for me to locate the sequence of outputs.
PROMPT_COMMAND=$'printf %"$COLUMNS"s |tr " " "_"'

Note: I very much prefer zsh (with ohmyzsh framework) but installing a new shell is not always an option.
