Anyone who browses the internet with multiple tabs open knows that doing so can both help and hinder productivity: while multiple tabs allow users to quickly switch between websites and documents, it can also clutter one's browser so that it is difficult to remember what tabs are open. Peek A Tab, a free extension for Google Chrome, may be the answer. Users can install it with just one click. Once installed, visitors can select a small Peek A Tab icon, which will appear on the upper right corner of their browser, to see an easily readable, vertical list of all currently opened tabs. Users can then quickly visit - or close - tabs using this list.
