I can't figure out how to see the bottom of the screen when using Pesticide. Maybe it's my lack of skill/knowledge - but I work on the premise that good software doesn't need to be explained just to do simple/obvious things. If I have to breakout the manual or dig through forums, THAT'S a design fail. The panel should behave the same as the browser's built in Inspector in that it acts as the windows foot and everything appears above it including the BOTTOM OF THE PAGE. Pesticide appears as an overlay that hides the bottom of the page. Edit: I'll raise to 4 stars since I just saw the 'move this banner' buttons. It still prevents seeing the whole page whilst moving around - maybe I have a very particular issue right now but wouldn't be as frustrated on other design debug issues.

It's great! I've been using this for a couple of days now and I had to remove any other extension that was trying to do the same thing. I would ask for an improvement if considered useful by others as well. The possibility of clicking the classes to copy to clipboard. Super helpful when coding and sharing info. Just hover, click - copied. Anyway, Great stuff! UPDATE: You guys ROCK!
