"Channel permissions override server permissions" notice

Can we please have a single string of text anywhere in the permissions settings page that states that channel permissions override server permissions? The only mention of that in any permissions screen is when you click the "Need help with permissions?" link that takes you to the permissions KB page.

I have apparently had incorrect channel permissions for 3 years preventing images to be posted in my main text chat because my ateveryone permissions were changed. And I had other permissions added because what the heck was I thinking?
