Also a little off-topic, but I just saw the topic linked in your signature Tuco and I was wondering, was the movement system ever tweaked and/or improved upon in the four years you kept that topic alive?
Marginally.
It was tweaked a little bit adding things like the instant "chain/unchain everyone" hotkey and so on.
Still far from ideal, nowhere near as practical or comfortable as a more traditional "click and drag to select" (see: Pillars of Eternity or Owlcat games as reference) and the lack of a proper formation control still hurts the game, especially when playing with mods that expand the party size, but hey... Better than it used to be.
And I gave up a long time ago on Larian doing the right thing when it comes to UI and controls.
