Add a summary to the print preview screen that shows the most common/critical settings.
Temps
Speeds
Cooling
etc.
Before I export the G code to SD card, I am always paranoid that I forgot to set something correctly (specifically the temps). So I have to exit the preview mode and check the settings again. And then re-splice it and finally export the G code to the SD card.
Maybe this is just my problem.
Better yet would be to have access to a grayed out the FFF settings window.
I guess this would get a bit complicated with multiple processes. It would have to show you the process setting for the current line/layer being printed.
