The skin is really great. There are a couple of areas it would be nice to have the font fix in, like the chat status, and status windows that pop in the page.
If you like this skin, but want chatting and other features on, check out my modified version of this script at:
http://userscripts.org/scripts/show/61324

One of greatest scripts for GMail ever to be created. Presenting a clean theme without stuff like logos, ads, useless functions or icons.
On the bad side I can say that the yelow highlighthing, blue hover color and other eye-candy beautifications do not work in basic html nor in standard in opera 9 or 10.
Still I give the script a 5-star.

Gmail in Blue:Professional skin not only creates beautiful blue tones for you nav links but also introducing many useful Gmail enhancements, such as hiding the Gmail logo, Chat and Invite boxes, Chat and starred icons. Also removes annoying ads in message pane and much more. I REALLY appreciate this userscript. It does nearly everything I have wanted done to Gmail since I started using it in Oct 08. Very nice!
