The Cross Server Prices / Price History Applet has a Show/Hide feature in the upper right hand corner. This also happens to be where the Firefox Add-in No-Script puts its Block Tab (which overlays directly on top of the Hide link, leaving only a pixel or two space to click Hide).
Would it be possible to move the Hide option to the bottom of the roll-down window when its active instead?
Let me know if you require a screenshot of what I mean.
