I just made a map in this style last night. I will post it here later as I don't have it with me. I like the fact that the color key is being used in the new styles. I've found use for that function in other maps as well.

In the never ending quest of mapping my campaign world here is a version of Tharo I did with the Jonathan Roberts style. It is a work in progress but this is the second time I have done a big city with this style. I have also attached flavor text with the pdf that comes from a supplement I bought from another company if you want to check that out. I did this map as a simple 1000x800 style map and adjusted manually with the scale. This tinkering with the map made for an easier export.

I pretty much know what the districts of the city are going to be but I have not marked them yet as I am still working on the fiction.

I don't need to see the interface change but I too would love to be able to export my maps ready for VTT. So I guess that means I am echoing Line of Site Export. However is that even possible to program in with the underlying technology? I don't know programming so I wouldn't know. It seems to me though that DungeonDraft and DungeonFog use a completely different technology to do their maps.

Honestly its not that hard to create line of sight within Fantasy Grounds, my VTT of choice for the moment, although Foundry looks pretty good too.

I'm including this image as they all go together in the package I am building. The first map leads to the cave entrance and the second map is the cave entrance.

This is a little ambush battlemap I am using to do some encounter testing for various systems. The crates on the elevated area to the east provide hiding places to ambush from a prone position with crossbows or magic against characters coming in from the north or south entrances to the cavern. Also there are two little nooks on the west side of the map both north and south where assailants can lie in wait. I might even use the pool of water in the middle as ambush cover for an underwater ambush.

The arrows indicate slopes that characters can charge up to engage the elevated ambushers. I put the arrows on the Gamemaster only layer so I can remove them easily when I need to.
