New close buttons too indistinct

I just updated to SoulseekQt build 2013.8.3 and the new close buttons on tabs are really hard for me to see with my bad eyesight. The "brush stroke" shapes and lack of color make them blend in with the tab text too much, and I've already clicked on them several times by accident, which never happened with the old design in previous versions. :( A more standardized "X" shape, a distinct color, or even just adding more space between the text and the button (if you're really set on the swashy colorless design) would help a lot!
