Same here. Overall, it's pretty good, I like it, I am impressed with their rate of improvement and progress.

For core apps I would love a rewrite of Dolphin. How does it not have Miller Columns? They're amazing, super nice to work with. In theory tree view should do the same things, but it's not as polished or clear. Apparently they felt the code as too complex, but I still feel it's a travesty they don't support them. Tree view is not equivalent.
