A basic mode with the following changes would be very useful for e.g. churches.
(when vMix is operated by less experienced people, but when transitions are still needed)

-showing the transition buttons and T-bar
-showing the status bar (always useful)

-hide the close buttons (can really mess up things)
-hide the add input button (not needed for a finished set up)

With this modifications the basic mode is also ideal for using a touchscreen.
