After some research(And remembering plants I forgot to add.) I found some more to add:
-Ferns
Many species are tolerant of high moisture, and they're pretty nice looking. Not sure about fitting the easy care requirement, though.
-Wandering Jew(Tradescantia species)
The name is weird, but this is a pretty durable plant. I'm planning to get one eventually, since it has some pretty varieties. It is another vine though.
Some people like to use orchids in their vivarium.
Umbrella Plant, especially the dwarf variety can be good, but I think it's better suited to taller give, since they can get as talk as 10 feet or more. In a shorter Viv you'd probably have to trim it constantly
There is a thread, "Ultimate Plant thread" stickied in the plants section and it's pretty useful. I used it to check my memory and for additional recommendations. It has a lot of pictures so you can see them, and firsthand experience with them.
