I just had a play myself and I like somewhere between 0.8 and 0.85. I'm not a designer though and lean a lot more towards clarity vs style.

When using it I wouldn't want to have to manually pick a theme based on the pic, as it would probably be a database gallery - but a choice of themes is great to have.

This is a good point, I will have to have a heart to heart with the alpha value.
