Mine is more metering options (to get all the channel meters to be able to behave like VU meters with -18 dbfs as 0db).
And a project information text export.
(P.S.: I know you can futz with the meter appearance via preferences but it wold be nice if it could match the options of Logic)
There is a key command for every track version function in cubase. So the scratch pad could not be faster than this. I prefer to have my alternative ideas right in place so that I can switch between original and alternative version. With track versions you can handle an alternative chorus idea, just for the drum tracks or for all tracks if you use track version id‘s. So I still couldn’t imagine any advantage for the scratch pad.
