Pommie:
When you press the full-screen button (upper-right arrow) on the TRP3 frame, the maximized frame appears underneath Titan Panel, making pressing the lower-left arrow to go back to normal size impossible (unless you first hide Titan Panel).
See screen shot:

If TRP3 could recognize that Titan Panel is active and maximize just below it, that'd be nifty!

• same goes for Bazooka and other databroker add-ons + the order hall bar.
