I find myself pressing Enter several times before running a command to
be able to find the beginning of the output afterwards, so I agree. The
prompt should stand out more.

It seems popular among terminal emulators to make bold text extra
bright. That makes the bold green prompt a bit too bright for me on a
white background. It's nowhere near as bad as yellow on white, but a
little too bright to be comfortable. Once I turn off the brightening to
let bold text be the specified color, the bold green prompt works well
for me.
One way to avoid all the color issues could be to just make the prompt
bold by default. That would probably make it stand out enough in many
situations. I think it wouldn't help much for programmers compiling
software though, because GCC outputs filenames in uncolored bold text,
so even a bold prompt would blend in among the compilation errors.
