Different icons for different default legend styles

[wayfaringrob]

Unless you hover, wait, read, and think quite a bit about what each of these tags mean, there's no real way to differentiate between 5 out of 6 of these legend options.

The 6th is different, but the poor design of these icons leaves me guessing at what's different about it. I would think about using these defaults if I could actually decipher the differences, but it leaves me longing for the wizard in ArcMap, which is significantly more straightforward and intuitive. Could this area be improved? The table frame gallery is a good example...

Glad I searched and found this one, as I ran into this the other day and couldn't figure out what the differences were.
