Thanks guys.
I found the movement system quite annoying when there was no monsters present, as I would like to move freely with out the step countdown. I also think that grouping movement should auto switch to your leader (when no monsters around).
I've been through a few different versions of the movement, and I'm still not entirely happy with it, yet I haven't figured out a way to make it quicker to use without sacrificing the strict turn-based approach. The grouped movement is currently a good compromise, but it could do with being slicker. Suggestions are welcome.

I'm not sure I understand what you're after here? Related, I'm not sure yet whether I want the user to nominate a 'party leader' or not. Later you'll be able to swap in/out members of your party, so the concept of a leader might not make sense. OTOH, having your leader grant certain bonuses based on class (eg. nominating a warrior as your leader makes everyone hit harder) could add some interesting tactical choices.
