Someone had requested this on one of the post and Mhamdi seems to have worked on it pretty soon. So here it is: “phpLD Custom Category Titles mod”

If you want to customize the titles of the categories pages and not limit it to the name of the category you can use the following modification.
Example:
Category: Internet
Custom Title: Web resources.

Category: Employment
Custom Title: Find you next job
