Oh and when you add a new track, is there any way to have the new track appear just below your currently selected one, rather than it appearing right at the bottom and having to drag it all the way up to where you want it?
I’m not sure if this method is quicker than moving up the new empty mono track, (it depends how many tracks you’re using), but you could …
Create a new stereo track (rather than create a new mono track) which will appear at the bottom.
Copy and paste the single mono track you want to make pseudo-stereo into it, (it will become dual mono).
Delete* or mute* the original mono track and apply the pseudo-stereo effect to the dual mono version.
[* optional: you may want to keep the original mono version in the mix: mixing it with the pseudo-stereo version produces a more subtle pseudo-stereo effect}
