The predefined header tags (<h3><h4> etc.) are great, however they are the same color as all linked text. When several are used in the body of a page or post, it's not clear what's a link and what's not. Ideally, clickable text should have it's own color. Just a thought.
I've created my own header styles as a workaround, but WordPress 2.6 likes to delete my custom tags when switching from 'HTML' to 'VISUAL' editing mode. Ugh. If there is a better solution please let me know. Thank you.
