My answer is somewhat boring, as it is technically a QOL issue :
Simple system to select characters X1 and/or X2/3/4, or select all, and move characters without any auto-follow, but only move who is selected to point clicked.
- irrelevant of if the characters are in stealth or not.
I endured the wonky system in DOS1. I beg Larian to fix it. It is a true hassle.
This, so much this.
Auto-follow drives me up the frigging wall!
