Titan Hearthstone uses the Titan bar to show your Hearthstone cooldown (and spell if your a shaman), it's location, and allows you to click on the icon on the bar to cast your stone . In the case of Shamans, it attempts to cast Astral Recall first, if it fails, then it uses your stone.

Options on the control

1) Show Text - Toggles if the mod shows the words 'Hearthstone' in addition to the icon.
2) Cast on click - Toggles to enable casting of your Hearthstone when clicking on the timer.
3) Show Location - Toggles to display the location of the Hearthstone on your bar instead of just in the tooltip.
