This is a simple addon that shows your reputations on the titan panel.
You can configure the plugin using the ReputationFrame (left-click on the button to open it). The reputation you choose to show as xp bar will be used in this addon bar button. The tooltip will show all reputations except by the ones you move to inactive.
