I made a post regarding Transport Controls being available in the Editors:

There seems to be alot of space with the default items in the Editor pages and it would be a nice feature to have.
I know I can minimize windows and so forth but there has always been alot of to and fro with Cubase from the Project Window to these Editors, something that the Lower Zone doesn’t really alleviate since you need to go to an Editor in order to access the Inspector.
When there was such a thing as the floating Transport Bar, there was no problem but in a way the introduction of the Lower Zone and (likely) associated transport section is a bit of a regression and I believe having Transport Controls available in all of the editors would go a long way towards making the program easier to use.
