I think it would be very cool if you could have a option when you are installing After Effects to have ether a Simple or Classic workspace. This feature could be implemented to other CC apps.
The Simple workspace would be made simpler. This would mean having rounded edges like how Apple made Grage Band , less things on workspace making it more simpler, and having cool new inlarged pannels. An example would be like the Character Animator Control Pannel, as it has sliders and triggers. I really like this design and I hope it would be implemented.
The Classic workspace would be like the workspace now.
This would be great if you implemented this into After Effects CC.

Why are rounded corners simpler than sharp corners?
Also, you can already customise the interface to hide as many panels as you want. There is even a workspace preset called Minimal to clear away a lot of the clutter.
