The first of these such 'tweaks' is to change how the Course category page is displayed. It is important to note that this will involve making a small change to the core Moodle code. This will mean that when you upgrade your Moodle instance to a newer version, you will need to make this adjustment again in the new version. Ideally, you should keep adjustments like this, sometimes called hacks, to a minimum as they can complicate the upgrade process. Always keep a record of the changes you make so that you can easily transfer them to your new instance of Moodle when you upgrade. Additionally, if your adjustment involves a feature that you feel should really be a part of the Moodle core complete with an adjustable setting via the Moodle browser interface, please make the request via the Moodle Tracker found at http://tracker.moodle.org/secure/Dashboard.jspa.
