Q103: Is it possible to overwrite or extend a scripts includes and/or excludes? How is this working?

A103 Sure, just go to the options page and click at the script's name you want to modify. A new tab is opened that shows the script's source code.

includes editor

Click at the "settings" tab (1) to get the *cludes editor shown at the image above.

Now you can select i.e. a entry from the "Original includes" section (2) and add them as exclude by clicking at "Add as User excludes" (3). The entry now appears at the "user excludes" section (5) and the script will not run at this page anymore.

If you want to make a script run at a page it originally shouldn't you have to use the "Original excludes" section (4). Again select a entry, click a the button bellow the section and the entry will appear at "User includes".

You can also add, edit or remove entries that are manually added by using the buttons (6) below the according User section ("User includes", "User matches" and "User excludes").

If you want to override the orginal includes completely just uncheck the checkbox (7) in front of the according heading. For example you have to uncheck "Original includes" if you want to disable the directive htt*://*facebook.com/*.
