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.

 @6ee90ca1 ditch Creality Slicer, every other slicer on the market can do that by default, works with all printers and is free. The big trio (PrusaSlicer, Cura, Bambu/Orcaslicer) anyway.
