One remark : why is it installed with such an incomplete oldfashioned CCS preset ?
I added rounded corners, removed the underline, added a modern font and it looked great.
Yeah, I guess you're right. I didn't want to presume that I could create a perfect output which would work with every color scheme, so I made output that would stand out against most color schemes.
For me it was important to make it easy to style so site administrators didn't need to do anything other than configure the plugin.
