Clouds, pinpoints & feathers-- a basic clarity question

[bluedawg]

I tried a search but couldn''t find much there...

What are the characteristics of these under 10x?
Is one type of inclusion more or less likely to be visible to the (naked) eye?
And what does a GIA plot that specifies "clouds not shown" mean?

Thanks.

oops, never mind. I found all the answers at the niceice.com tutorial.
