Feedback has been hot and cool on them, still trying to decide if they are worth it or not.
Btw, Does not fade away in IE8 with hover.
IE8 can't do anything fancy.
Having them pop out of existence is jarring; maybe have them fade to near-invisible.
I'm not really seeing why I would want the label of the section in question hidden when I'm dealing with it, and at least for me there's not really a parity between 'dealing with' and 'hovering over with my cursor' anyway, unless I'm copying the text. The bright orange color and the constant flashing on/off just adds visual noise and makes it difficult to really read the labels anyway, imo.
