Switching theme panels is now instant and flicker-free
Switching between different theme panels is now incredibly smooth. Previously, every time you switched panels, the system would tear down and reopen the entire window, exposing the dark background for a split-second flicker. Now, the system quietly keeps the panels you've opened (up to 6) waiting in the background. When you switch, it simply injects the latest numbers and brings the panel to the front. This means any previously opened panel reappears instantly with zero flickering, and the window itself never closes and reopens. It's like changing theatre sets: instead of dropping the curtain and tearing down the whole stage, they now have multiple rotating stages fully prepared underneath, seamlessly spinning into place ready for the next act.
