I too would like to nested view to be a supported feature. I miss it so much <img src="https://www.ubbcentral.com/boards/images/graemlins/frown.gif" alt="" />.
I find neither thread ot flat mode to my liking. In threaded mode I end up clicking over a hundred times in large threads. Then scrolling down to find the next thread I want to read. Where as in flat mode I tend to get lost in quotes and side conversations that make no sense without reading what the post is refering to.
Nested view solves both of those problems for me and if people don't like it the can always turn it off.
