Just upgrade to WordPress 2.7 and wonder how to enable Google Gears?
Gears is a plug-in that extends your browser to create a richer platform for web applications. You can use Gears on websites to let access information offline or provide you with content based on your geographical location. To install Gears, visit http://gears.google.com. It’s pretty cool and really speeds things up. For WordPress it is used to store all images and other web page components from the admin area to you local PC, speeding up access and reducing unnecessary web traffic.
Prior to 2.7 the admin dashboard had a “Turbo” button at the top… you’d click that and if you had Gears installed you were good to go. In WordPress 2.7 the “Turbo” button has been removed.
To enable gears login to your Admin section and go to the Tools SubPanel. Once there you have the ability to use Google Gears to make WordPress work in a “Turbo” mode. In addition, the “Press This” bookmark tool is detailed.
