Personally, I’ve switched to VexCode. It fixes every problem I had with VCS (no multi file support, no keyboards shortcuts, saving to a proprietary format, having to use some bad python script to make it usable)
PROS does have some advantages, though. Since it is much older than the V5 API, it is better documented. That being said, it is my understanding that https://help.vexcodingstudio.com works for VexCode.
