I'm trying to use a Core2 with Micropython with the following IDE (Windows 10)

UIFLOW Editor - to fancy (how can I change the color of the background? - disconnects a lot
Thonny - freezes my PC when using REPL and play with large strings
MU - can't open the filemanager, reboots my Core2 when I try it
VSCode with m5stack extension - sometimes the button to connect is there, sometimes not

Is VSCode with Pymkr an option? Did not try it so far.

What else is on the market?
