I've posted some. Let me post mines...

DirtPath - lays a more attractive path. I highly suggest this.
SwampTiles - lays swamps...
WaterPath - Lays shallow water

All of these are great for covering lots of area... but should of course, be gone over manually afterwards. There are probably more out there, but usually they're stuff like lava paths and such... nothing really useful. I used to have one that would detail a level, but you will most likely be scolded for using anything like that.
