See I don't have the patience (or indeed knowledge) for that. I love Compact because it's exactly right and all I have to do is add a new header/fiddle with the colours.
See, but there's the thing, Dreamwidth makes fiddling with stuff like the font and the widths and arrangements of things as easy as changing the colors. So, yes, it takes some time, but it is pretty easy and you don't have to muck about with code to do it.

This is what worries me. I'm always worried that tinkering will break something and then I can't get it back.
They won't let you do anything too dangerous with their own controls. I'd just only make a few changes at a time so you can keep track of what caused what. Put your journal in one window and the settings in another side by side. Change something, refresh, change something, refresh, etc.

Let me know what your base style is and what's bugging you and I can probably help you figure out how to change it.

Yikes. I only use it very sporadically, f.ex. for mood themes, as it'd take forever to upload them all individually.
I've only used PostImage for a few pics so far, and I'm never going back to Photobucket. Should have got rid of it years ago, tbh. It's always been a misery.
