I like that the Color Picker stays up so I can highlight and re-color another piece of text. Any thoughts about adjusting the hover so it doesn't obscure the text box (how about making it hover above the editor)? 

Error checker is subtle and nice. I didn't notice it until I tried to purposely screw up a tag.

Apparently not. I wonder if it'd be possible to add a linking function to quote, such as [quote name=Mahz link=2345802] to link directly to the post in question. Quotes are easy to modify on your own (especially if quoting across topics) and sometimes the original context is useful.
