Dark Mode/ Light Mode. toggle

I am sure that there are many churches which do not have a dedicated dark room/area and are within the main hall.
this gives issues when bright light can drown out the screen.

Having the ability to toggle between light and dark mode is very useful.

Our desk is in the corner which gets bright sunlight in during every service, and at times the text cannot be read.

When it was first setup it had light mode, this has now been taken away and I would like the toggle back please.
