I don't remember where I got them, but I have ADFs of Kickstart & Workbench 1.4 Alpha15. They're fun to load up and play with in WinUAE, I strange mix of Workbench 1.3 with some 2.0 stuff thrown in. I was going to include some screenshots with this message but I can't seam to get the image manager to work (all I get is a small window with a Xoops banner, a pulldown gadget with nothing in it, a button beside it that doesn't seam to do anything, and a close button.
Workbench has it's own window on the Workbench screen; there is the ability to view "All files" and "View By" icon, name, size, etc; windows have a new "Up Arrow" gadget that brings the Workbench window infront of ALL other windows. There is also a WBStartup drawer and some interesting shell commands like "AddMonitors" and "IP" but everything else is basically 1.3
