Personalization Pages in eLearning

Hi, I would love to start a discussion about what options people are including on personalization pages.

See an example here from eLearning Designer

Some features that I think would be valuable for learners to toggle would be:

>Background image- (Turn off any background images and replace with fully white)

>Light or Dark mode (Toggle between a white background or dark background)

>Dyslexia text - (Change the regular font to a dyslexia friendly font with larger spacing, and left justification)

>Audio Narration- (Have narration on or turn subtitles on)

While all eLearning should be designed to be accessible, there are sometimes organization branding constraints (often not accessible themselves) that prevent just using a Dyslexia font from the onset.  Or design features that look better for most (for example maybe a slide with centered text and background imagery) but needs to have the option to be adapted for those that it doesn't work for.

Anyone have a great personalization example and/or triggers and javascript code to share?
