Starting with v1.06 there is a configuration screen with several options: including ignoring losing rep for hated factions and adjusting the display font size. All slash commands have been implemented here for easier use and control.
However, if you still want to use the existing slash commands, you can type /RepTrackerHelp to see a list of slash commands available. Currently though new options are only available in the configuration screen.
Reputation Tracker shows how much your reputation with factions changes during a session. Perfect for those times when you're farming faction rep.
It will also tell your your current standing with those factions you have changes to, what percentage you've reached so far in that standing and how much rep until you reach the next standing level. The current standing report fades in when you mouse over the mod, and hides when you don't to conserve screen space. It also will highlight the color of the standing and rep remaining depending on the current value. See the change log for more information (added in ver 1.04).
The totals are reset whenever you log out of your character.
It also has a text summary report that you can enable or disable with a command option. This feature is defaulted to off since I doubt anyone will use this anymore. It was a early beta feature before the UI was fully functional, however I left it in if anyone really wants it. This doesn't have the same full functionality of the UI though.
