Restoring time lord themes
After you have added a time lord theme, you can restore a time lord theme by looking for it in the Saved Time Lord Themes listbox on the bottom right side by double clicking on it. If you wish to delete a time lord theme, click it once and the (-) button to the right will become active. Click the (-) button and it will ask if you are sure; clicking yes will remove this theme from the list.
It is a good idea to click on the Save button once you have made changes to what themes you are using if you want to retain this for your next session. By this I mean the Save button sandwiched between the Available Methods listbox and the Selected Methods listbox, not the Save button at the bottom of the Time Lord Options window.
