Provide users a method to set an account wide Font choice

You have added a feature that forces the disruptive choices of a few upon the many without the ability of those affected to disable those actions.

I would like the ability to set a font and size that would apply to all text within the client or logged in web page.  I would also like the ability to disable emoji/emoticons   These too, are frequently used to be disruptive.

All that is needed is a tickbox for each feature.  

Override text with selected default client wide font?

Disable showing of emoji/emoticon.

This should be very simple.  I cannot be the only person who finds the new added features more than a bit annoying.
