That or a separate mini module with on/off and Edit type buttons.
I think that would be best, but suggested changing a button because I figured that would be more doable (i.e., appear in an update sooner

) compared to adding another control bar module.
Ripple Edit is not a mix feature.
Yes, I guess that makes it a non-starter. My reasoning was that people get tripped up by offset mode and ripple edit mode, so having them together might make those two functions more front of mind and lead to fewer errors.
