1. The Page Name does not include the query string (or GET variables). Hovering over the page name will reveal the GET variables or, alternately, you can choose to show them as their own column in the settings page.
2. You can choose to stop logging admin accounts under Tracker Settings, the option under Widget Settings just stops displaying admin results but the one under Tracker Settings will stop admin accounts from being tracked at all.
3. I can change this if you desire? I will make it an option in the next update for you :) I'm moving house at the moment but I should be able to do some work on the plugin in a day or two.
Sorry about your troubles with my plugin, if you have any more requests please either post them or email them to me (firstname.lastname@example.org).
