I'm using Creality Slicer for these Ender-3 S1 printers and there's a python script that mostly (but not always) adds a thumbnail to the gcode. 

Also, Creality Slicer often loses the ability to show some contextual menus so I quit & relaunch it a lot.

And I really wish I moved this printer off my desk before starting a 12 hour print.
