Need simulated stereo

When you are stuck with a single good track because the other is unusable and you have to clone it for a stereo track; you typically end up with a very unappealing mono sound.
No depth. Very dull to the ear.
A simulated stereo effect was needed and I was surprised that Audacity didn’t have one.

Steve Daulton’s Pseudo Stereo plug-in was brought to my attention.
It works great! It added a very convincing depth to the mono recording that was just as good as a good stereo recording from this source.
The only addition I would make would be a PREVIEW function; but this should be added to the regular group of built in effects to Audacity!
