Is it at all possible to disable colors for a particular user and default them all the white? It just... Is hard to look at them, I dunno why, but I can't stand them.
Also, Headers leave too much space after them for my taste.

Maybe a simple button on each post that lets you toggle its colors on/off? That's be simple.

At the moment, you have to manually control the spacing between headers and content. Compare:

[hider=Two line-breaks]
[h1]Header[/h1]

Content
[/hider]
[hider=One line-break]
[h1]Header[/h1]
Content
[/hider]
[hider=No line-breaks]
[h1]Header[/h1]Content
[/hider]

Click "View Raw" to see the code. I had one-line-break in mind when I wrote the header bbcode.

Headers, hiders, and some other bbcode need to be tweaked so that they eat the first line-break that follows. Until then, it kinda clutters the bbcode when you have to remove line-breaks to remove extra spacing.
