;-) Now, this is shaping up into something sharp!
:-) In the first shot, some of labels in the windows have underscores under one letter. This suggests that it will be possible to navigate through the window, activating gadgets, etcetera, with the keyboard, instead of having to switch to the mouse repeatedly. This was one area where Windows® had a feature that AmigaOS didn't. Now it seems that it does. This is a welcome addition.
The drop down arrow looks a little awkward, but it's probably one of the details still to be addressed.
Also, the brushed metal is gone from the windows, but it remains on the dock, where it looks good.
The title bar has a shadow, it seems. Or maybe that's part of the background image. Either way, it looks good.
:-) In the second, there are icons in the prefs drawer for new features: AmigaInput, Asl, DefIcons, USB, etc. PartitionWizard looks impressive: uncluttered and easy to use.
:-) In the third, the NotePad and SnoopDos windows are hanging off the edge of the screen. Directory Opus (version 4?) is running in a window, and making use of the new anti-aliased fonts and system gadgets. It's also showing the contents of a "kickstart" drawer at the root level of the boot partition. Ram Disk: has only two drawers now instead of the current three. Interesting stuff, here.
:-D All in all, this is impressive, and I'm eager to get my hands on a copy!
