Simple request, Hind/Show Helm toggle on character sheet.
 

Is there a addon that adds a toggle to hide/show helm without having to go into my options to do so?

I know I'm laze, but it's the little things that count : )

Yes please!

Wykkyd's Full Immersion have such option. Hide/show helm keybind and auto hide/show based on if you are in combat or not.

My wife wanted something similar a few days ago.

I've uploaded the addon here (it may take some time until it's approved):

I will throw mine in the ring as well. It features a slash command to toggle as well as a configurable hot key.

I will look into adding a helmet toggle button within the apparel window. I have yet to play with dds files or doing anything with windows so I won't give a timeline but I think the idea is cool and I want to see it added.
