On the other hand, in one of the fights past the north gate leaving Cyseal, if your party is spread out (or if 3 are spread out, and one goes up the wrong path to join them and triggers the fight... hypothetically) it can take a while for the mage and a couple boars to head around the long way, so I could certainly see using a 'skip movement' function.

If the game is balanced well there should not be a lot of very easy fights, but with the freedom to explore wherever you wish, you are probably going to fight a few higher level opponents early, and get to lower level opponents later, so a 'skip to my next turn' function could be useful. I'm not sure that would be needed enough to justify the effort to implement, though, and if used too much could cause problems (you could miss seeing behaviour and tactics used by opponents in non-easy fights, etc).
