I am a bit stuck in a pre-Blueprint world. So I was having a look at it.
I loaded up the current, release of pier, and it is very clean and ready
to be styled. I miss the tree view, has it gone because it doesnt fit in
the layout?
Blueprint looks cool for some applications. I have one site which has a
fairly fixed layout, so blueprint appears to me to be an ideal solution
for that, but not, I fear for pier in general.
This appears to me to be a better fit, for general blogish/corporate sites.
