A really good addition would be a way tp make maps and dungeons. Everything available is very dungeon centric abs nothing to really make detailed world maps.

I don't know that DDB will ever add or even need to add a map maker (it would be nice admittedly).

They currently dont even have a VTT (which is planned), but that will probably be able to import maps you've made using other map making tools.

Heck, they currently dont even have a centralized list for maps they already have.

That's my 2cp on the suggestion anyway.
