Party (group) moving through caverns?

Morning all,  Loving the system (even with quirks) as it allows me to Game again!  Have a guidance question.  I'm DM'ing and can handle most all that is thrown at me, but... how do you all handle a party moving through a dungeon map.  Do you use a "party" icon and then introduce the Party tokens when there is an encounter?  Trying to herd cats or do I just let the cats wander where they will and let loose the Hell Hounds of war...  Just working on the timing and movement.  Advice appreciated (yes that even includes sarcasm) 

Use things like Fog of War and Dynamic Lighting movement restrictions to keep the party from getting separated. How did you handle it in person? I like the idea of a party token (or simply the party leader) maybe add-in a side-bar showing the marching order.

I let the party members do as they like. After two or three who went other ways than the rest of the party suddenly had to face a serious monster alone (and did not return to the group) they are now eager to stay close together. And that isn't DM arrogance - I place the monsters before the party comes, and most of them don't wander.

Agree with Linda B. I check "update on drop" and it keeps folks from just wandering the caverns to search them all out without dropping their token. I also use the occasional trap, and the occasional monster with a reason to be there. Dungeon dressing has meaning and purpose in the game, and they figure that out quick and tend to watch for signs: blood splatters for re-settable traps, monster leavings or lair markers and so-on. Have a favorite that I didn't think would work but worked amazingly. 

I get a marching order. The lead moves first. If other split off they will soon learn its not a good idea. I get them to move one at a time to see if the run over a trap without checking. Checking takes time so movement is at normal not dash. To enhance there experiences describe changes in the dungeon. Undead smell really bad, light is reflecting off the wall as if its wet ( maybe fresh blood splatter ) , u step in a small pile of something, There is a taste of cooper in the air. 

I've warned my players that any movement becomes 'canon' - if you move ahead of the group and hit a trap or a monster sees you or whatever... no take backs.  There are times where they'll start moving into an area and I'll just say, "hang on a minute there" so I have a chance to read through a description of the surrounding scene, or if I need to do something on my end.  It hasn't been an issue for my group.  But I do have the ' token lock ' script set up, so if I need to quickly stop all the players from moving for some reason I can do that as well.

Thanks for the replies all.  Much appreciated.  I do use the Dynamic Lighting... but I've not played with the update on drop... might be a few surprises.  Each time is a new learning addon to the game.
