Activate/deactivate accessibility options e.g. display / color filters

Hello, I have been a user for many years and really value this product!

One type of action I would like is to be able to activate and deactivate accessibility options. The specific case that's top of my list is: enable the display filter and filter type. I'd like to be able to toggle between color and grayscale with just a gesture.

If this is possible already today, kindly point me to how to do so. If not, please do consider this for an enhancement soon!

Thank you, keep up the great work!!
