I've managed to get a few mesas, canyons and buttes together.

I decided that the compass was too big for the standard 100 mile scalebar (the one above really is 500 miles at default scale), so I made another 2 to go with the smaller scale bars - removing a level of detail for each one. I hope you still like them.

Here's a quick scale bar and compass.

I think I have most things covered, though not specifically mangrove. There is a swamp fill, and a tropical forest fill, so you could make a mangrove using a patchwork of those two. However, unless your mangrove is the size of a county it won't really register as more than a dot on a world map.

@Don Anderson Jr. There's a hole in the middle of the larger ones, so each of them will look different depending on where you put them. You can add a bump to any of them by putting a bevel or chameleon hill in the centre.

@Royal Scribe Yes, I think cliffs will be first tomorrow morning, unless anyone else comes up with a request I just didn't think about.
