It's a little on the 'bleeding-edge' but it's surprising that I cant think of an alternative that blends structured data properties, markdown notes and your file system.
There's still a lot to build out, but it's a courageous effort!

It's an interesting concept. I don't like the file browser. Seems hacky and missing some basic view options. For my money, I think PathFinder does better with that part. I don't have a case for using the file browser as a "database" for adding notes to a file other than the Spotlight comments we already have. For custom attributes for a file, DEVONthink does far better. But cheap is good for many users, I'm sure.

Proper assessment Paul~!

Devonthink for the power win!

I'm downloading it right now: the screenshots looked great - I wish Finder would expose some kind of directory notes as you navigated, or even more compex document types without having to open then: then I realised that's basically DEVONthink.

And as someone invested in DT, this seems like it's replicating that functionality - though I can see it being possibly of more use for working with project/directory structures less aligned with DT's more *textual* document models.

All I can hope is that some of the ideas this explores and exposes lead to a buyout from apple; It'd be great to see a little more love applied to local file systems management.

Hmm. It seems very early days for this, more a public proof-of-concept. It appears to be a wrapped browser experience; lots of file types I'd expect to expose previews are not doing so. Navigation is cold - it's ignoring icon files and tag colours in the interface, flattening everything. It feels like a lot needs to happen in the interface to accentuate the things that make this distinct and of use; I'm surprised that the screenshot-tease of per-directory text descriptions is either hidden or tucked away. Maybe these are features waiting to be turned on.

well said.
folder and file skeuomorphism is totally dead to just about every generation younger than me... and that notion only rose on its development of database structure.... >> what I'm getting at is that finder is getting shockingly irrelevant as we grow 'generation-mobile'. I appreciate that they're adding layers/properties into an active file structure..
totally get what you mean about DT!
