Icon style: Cursor, Round Corners, Opacity.
Change icon opacity on mouse over/out.
Better and working close icon.

SVG container bounds just don't work for me, use a font icon.
Remove the barameter stylesheet, not needed after all.

We are using an UV like icon now, not a tab.
Serve JS file with correct mime type.
Add the cool slide effect that UserVoice has.
Add actual email sending support.
Rotate close icon 180 degree.

It's not symetrical; this isn't great either (rotates too much), but
is preferable too something askew. With the slower rotation speed
its kind of ok though.
