So some of the styles aren't great. Some are unreadable. I love the darkroom style, except the background within PMs are impossible to read due to how close they are to the text color.

So in preferences I noticed the Edit CSS button. Like a monkey I clicked on it and thought I found the write line to edit. All I edited was the color under the form portion of the css. After that, I got no changes that I could tell, but was no longer able to edit darkroom css.

Instead I get a blank box. I can edit other CSS though just not Darkroom. Darkroom still looks exactly the same to me, however Frank and Buck say that Darkroom is white not charcoal. It seems I broke something. Apologies all around if that's the case.
