Switching between interfaces

To be honest, I don't like the new interface, which is why I created this proposal.
I want people to be able to choose which interface suits them best.

how do i see this idea?
A separate item (Interface View) will appear in the appearance settings, there will be a choice between the old and new interface (old interface / new interface).
Initially there will be a new one, but users will be able to switch to old interface.
