Grep is a stripped down Data Broker display mod that channels all updated data to Blizzard's ChatFrame3.
This was written merely to see if it could be done. It may be completely impractical for day to day use. But who knows, you might find that you like it.
Usage
/grep add <mod name> - Puts a data mod on the filter list so that it will no longer be processed.
/grep remove <mod name> - Removes a data mod from the filter list
Using either of the two without an arguement will display a list of data mods currently on the filter list.
If you do not have a third chatframe already, right click on one of the chat tabs, select "Create Window", and name the new window whatever you wish to call it.
