I have to say the same thing as both the above. “Thank you so much! I highly appreciate your work, it’s people like you that make WordPress a joy to use.” and “I didn’t know how absolutely addicted I was to the plug-in until it didn’t look quite right with WP3. Hope to see an update soon!”.
What I am seeing is…
(a) rather grainy look to the characters in the side-bar menu and the hover menus
(b) a small white line to the left or below each of the icons (depending on whether you are using custom width or not)
(c) this gets worse and the sidebar line spacing increases as the sidebar width increases), and
(d) another small white line below the left pointing chevron/triangle which connects the hover menu to the sidebar which appears when the hover opens and follows the hover menu selection up and down the sidebar.
But I still prefer it, warts and all, over Matt’s original. I just add the second option of blue menus to the mix.
