Many thanks for your response and your suggestions for training resources look very interesting.
My query was not alluding to the UI between FCP7 and 10.3, but rather the previous version of FCP X vs 10.3.
The toolbars (and much else I’m sure) between these “X” versions is quite different as you know so there’s a lot to learn.
Thanks for putting me on the right track!
Cheers
