Protocol when opening lanes improvements

Would it not be better when opening lanes for comping that Cubase disables snap and also changes the pointer tool to the comp tool automatically?

Yes, this would be great !
As a workaround for now, i can imagine that you could make a Macro for this, making your workflow abit faster.

Kind regards.

Yes.
The macro has one problem though.
There is only a toggle on/off ( as far as I can see ) for snap so if your snap is already off it will actually turn it on.
