What was fixed

All of these came from real use, and all of them were the kind of small thing that quietly gets in the way.

• Using your own nozzle model now works. Pick any object and it is fitted to the print for you — tip on the layer, right size — and applied straight away.
• The Hot Band switch responds immediately. Turning the glow off no longer needed a second button press to take effect.
• The Surface Detail dials do something you can see. They were wired up but far too quiet; their range has been recalibrated, and the default look is unchanged.
• Reset Settings to Defaults leaves a working print. It now takes the rig apart, restores the factory values and prepares the print again from scratch.
• One click folds or unfolds the whole panel. And the panel opens folded every time, whatever you left open.
