The alpha capabilities of Viewer 2.0 permit a great improvement in shoes; they avoid the problem of dueling alpha textures that make some things that shouldn't be transparent transparent. (Now to see whether I can get improved versions of all my favorite shoes...)
The same facility improves the appearance of corsets greatly. No longer do you have "invisiprims" that make things behind them look transparent! The House of Alisha has new products that take advantage of the new feature, and I've bought a gown. I still have hopes of combining a tiny waist with prim breasts.
