Remove UI elements via configuration / Customize UI

[murezzda]

Is your feature request related to a problem? Please describe.
We do not use the local save function for our use case, thus it only confuses the users. It would be great to have an option to remove UI-elements if they are not needed.

Describe the solution you'd like
I've provided a simple PR which passes a parameter from the intialization of the transcript-editor to the player controls. This would solve my use case.

Describe alternatives you've considered
If other people are also interested in selectively hiding UI-elements, it might be better to have a more structured approach to customizing the UI. Maybe a configuration file which specifies certain aspects of the application.

Additional context
Will provide a simple PR with a straight pass-through parameter, if interest is there it would be possible to extend this to other UI-Elements with a more structured approach.
