Perfectly implemented. Although the [Home] and [End] buttons on the keyboard can be used to quickly jump to the top and bottom of pages, being able to navigate directly to a specific interface group, change a setting and then click to get the bottom is superb. Should be core! ;)
In short: The more add-ons you have, the more you need this one!
Locating the right permissions-set instantly is what this add-on is all about. The sooner you install this add-on when setting up your board, the more you'll really appreciate it. However, no matter when you install it you'll always cherish it.
