Well, this is sure to come up on next week's (well, later this week) Accidental Tech Podcast. John Siracusa (one of the hosts) used to write those twenty page reviews of each major release of MacOS on ArsTechnica. He and I both miss the spatial Finder. I'll try this out tomorrow for sure. If I wasn't worn out from a busy weekend, I'd try it now. I can't wait to see how this holds up.

OP: whether this delivers or not, it's a concept that concerns me. Thanks for caring about this and doing something about it.
