Had great scrollbars. When dragged there would be a shadow to show where the bar was. So you could go back if needed. Also the first platform I noticed that you could middle click the scrollbar to move directly, or control click the titlebar to lower. Though those conventions may have been from Motif?

It listed wm hot keys on the window menu and had vector icons. Yes, believe it was the best desktop of the era.

Would like to see an improved version of it, not merely a faithful reproduction. I hesitate to say modern because it often means dumbed-down. But made for higher resolution would be great.
