It is a smooth upgrade, but allow more customization of UI placement

I am a user who uses Final Cut Pro X extensively with two/three screens.

I remember that Final Cut Verson 10.2 had very useful UI that made everything convienient by placing all the effect options at the center of the main editor window so that all other features are kept clean such as the viewer. With 10.3, I am impressed that it kept a good deal of things faithful and stable for my video editong projects. However, I am having a tough time finding generators, effects, titles, and transitions being in one place. Also, the editing tools that are at the viewer should at least be allowed back at the main editing window so that the viewer can remain free of other things exept for view size.

I wished it had more customized UI placement of editing tools so that I can get it back closer to the 10.2 version and keep things modular.
Until I get the chance to have modular UI, I will have to toy around with the new UI to access the generators and text in addiiton to the effects and transitions
