“It’s a good idea though, and there aren’t even many of those in Tahoe.”

A few thoughts after reading Gruber’s take on Finder and its new auto-sizing columns:

1.
Column view as a concept and when done well deserves to be in the UI hall of fame. It flew and still can fly high in the Finder, and it was the unsung hero of both the iPod and the iPhone. It’s really fun to fire up NeXTSTEP 0.8 in Infinite Mac and see its first incarnation.

2.
Apple decided not to ship the auto-sizing columns a few years ago, hiding it under a “defaults write” incantation as a sort of a beta, but then seemingly just launched it this year without any changes. There are some charitable explanations – perhaps the beta was hard crashing Finder and the released one no longer does? – but in the current zeitgeist I’m feeling that it’s something more like this: the people with taste who were stopping it from getting launched in the bad state were either sidelined or are no longer there.

3.
And it is a bad state. It’s a first draft made public. Like anyone who deals with layouts learns over time, things like this one need careful min and max widths to have certain good pleasing and stable visual rhythm. They might even need a scale or a grid on top. And the fact that the width accommodates only visible objects doesn’t seem to make sense. The top hand doesn’t know what the bottom hand is doing, and it feels the feature is incompatible with itself.

This feels like an old Unix windowing feature, a sketch of an idea for GUI nerds who get excited about just the cool concept alone, ignoring the execution. Although, to be fair – this is opt-in and buried as the last checkbox inside a pretty obscure window. This might still be GUI nerd territory.

So Apple really did think we’re going to love Liquid Glass, huh?
