One of the coolest stock features of Drupal is that it can display tables of node editing/adding activity to general site users - both for all activity on the site as well as per user (on their profiles).

Some of you may be familiar with this functionality from social networking sites like Facebook (the Wall on user profiles), and thus know that sometimes all information shouldn't show by default in these listings.  For example, you may not want to display every edit an admin makes to somewhat-static page content. 

Guess what?  Drupal's so cool - it not only shows you tracker info, but also lets you customize the display of it!  All you need is to firstly activate the tracker module, then install Views and activate the stock-packaged tracker view.

As with any other View on a site, you can customise your new tracker but be sure to keep its location and name unchanged; that ensures it'll over-right Drupal's default tracker.

Now, if you want to also customise the tabs labelled 'Track' on user profiles, you'll need to clone the view you just activated.  This new clone you can call whatever you wish - such as 'usertracker.'  The usertracker can be again customised in terms of fields and filters etc...  Note: do not change its location - make sure it is 'user/$arg/track' so that Drupal sees this new view and loads it instead of the default.  Save the view et voila; it should show up on user's Track tabs; this affords you tons of flexibility to show/hide node types, add header text and stylesheet calls (in the view header) and much more! :)

Remember, you can re-write the URLs leading to your user trackers to sync em up with how you've setup your general user profile aliasing; just be sure to write the appropriate rule in the user-tracker settings of the Pathauto module (e.g. 'community/[user]/track').
