- Cannot close WebDev panel with clicking on WebDev extension icon again. - Cannot see which tool tab contains enabled tools - Switching between will more comfortable by hover, not click

I love this extension. I've been using it for years. My only complaint is that not all features were moved over from the firefox version. Most important of them is the disable javascript feature. Wish this feature was added to the chrome version... Otherwise a definite must have.

It's a great tool, but the menu doesn't readjust itself after resizing the browser window.
