Google Chrome extensions can be truly handy, but there's at least one feature power users have been clamoring for since the beginning: the ability to hide an extension's browser action button. Good news, Chrome Geeks: the Canary build now lets you hide extension buttons.
Just right-click the icon you want to disappear and select hide button, and it's gone. If you should happen to get removal remorse, just head to chrome://extensions and you'll find a show button link next to any extension you've previously hidden.
Yes, you could already drag-to-resize the entire browser actions area to hide any buttons which happened to be on the right-hand side -- but now you've got full control over which extensions get space on your toolbar and which don't.
At last, extensions which you can call from the context menu or invoke with a hotkey don't have to chew up valuable toolbar real estate in Google Chrome.
