Yes, the other top tip is that in general for a VTT, all of the stuff which is moveable is not on the map itself but is in the icons / tokens of the VTT. All the fixed stuff is in the the background map. So maybe doors are a bit of an in between. If you like to have your doors move then dont put doors on a dungeon. But maybe its easier if you map them. Some VTTs will calculate the light source / pattern or the player visibility / Fog of War for you. So if you have the doors moving then it can change when you open them. Not sure how you might choose to do it but its something to think about.
