First:
Please fix the Insert handling and remove the hidden mouse-over buttons. If you work a lot with Inserts effects the current style is terrible.
Workflow shouldn’t be depending on where you come in from with your mouse pointer + a timer for the hidden button(s) to show! Buttons bigger than the background insert slot is a terrible way to design something… I really don’t understand. PLEASE PLEASE PLEASE Steinberg fix this. It WAS good before (I don’t mean that you have to go back - just make the current version better).
Second:
We can’t use plugins on top of the mixer while working in the project window. Those of us who use two or more screens are not happy with this.
