# The Preferences Window: Extras Tab

This is where you can get optional things installed without needing a separate installer. You can also select your favorite script editor that will be used when you want to edit a separate “Run Script” action.

## USB Access | USB controllers, like the PowerLinc V2 and ActiveHome Pro, need an extension installed that permits applications to access them. The extension that Thinking Home uses is little more than a text file telling the operating system to allow access. It contins no software, so it cannot crash and it will not interfere with other software.
## Desktop Remote | You can operate your devices directly from the Finder. To do this, drag a device from the Installed Hardware window to the Finder. Then you can right-click or Control-click on the newly created Desktop Device to operate it.
## Web Access | Thinking Home can respond to web requests when Web Access is enabled. Just check a checkbox and type in a web address.
## Sherlock | Many people who have already automated their home have been exchanging a wealth of tips and other useful information in user forums, wiki’s and newsgroups. The Sherlock plug-in performs a quick search of these to find answers to your questions. Note that Sherlock may be unavailable on Mac OS 10.5 and later.
## Edit scripts with | If you create a “Run Script” action using a separate script file and then want to edit that script, Thinking Home will hand off editing to your favorite script-editing application. Apple’s Script Edtior is adequate and is free. By far, the best such tool is Script Debugger from Late Night Software.
