I know I can opt / Drag insert FX between channels / tracks in the Mixer window but if you are working in the Project window its not so easy. I never realized that I can’t select an insert FX and copy it, select another track and paste it in to a slot there.
I had a job yesterday at a location with a single screen where this started to drive me nuts. So please
1 : enable effects slot copy / paste
2: let me alt / drag an FX insert in the Project Inspector ( sidebar) and drop it onto another track and have it copy to an empty slot there.
