Where do you like to use the Stereo Expander?
Do you have certain scenarios/sounds/songs where you like to use it?
What are your settings for the situations?
I think it has some really interesting properties, I am not 100% how best to use it, hence asking.
Thanks. 
I stick one on the master and toggle it to hear mixes in mono.
There are some phase effects I like but don’t want the obvious panning so often I’ll squeeze to mono or almost-mono.
At times I will widen some backing vocals too.
Also, here’s plugin that makes the bass mono: the freeware BassLane VST effect plugin
Basslane is a good tool on the master bus to keep all the subbasses mono under a pre-defined frequency. This is very important especially for electronic music. Because all subwhoofers are mono. Also in the club. So it helps to keep the bass mono compatible. I use it in all my productions.
Yeah keeping the subbass of the whole thing mono would take one extra rendering edited with multiband send+ stereo expander, but I’d actually do this instead of having one plugin more in the list.
I’m using this technique too, but I guess it’ll take a while till i’ll play a system big enough to hear this 
Do you hear a difference when doing this at home?
Usage for the expander: Making stuff wide in the mix. have to admit i almost never use the width parameter and even dont really know what it does 
Also, sidechain something mono w/ stereo expander + highpass filter! Spaaaceeee ^.^

On a good sound system you will notice a difference with the subwhoofers. Also with good pro headphones you can hear a difference. The bass and the kick’s sub do sound fuller than without.
