I would really like to see an opensource or freely accessible version of HyperCard which does user interface right. Still annoyed by the rug-pull the LiveCode folks did for their opensource version and wish that the OpenXTalk folks would get some traction.

One of the most effective menu implementations ever for me was Altsys Virtuoso on NeXTstep's right-click (to pop-up the main menu at the mouse cursor), drag-down to Modify, then drag right to "Punch" or "Union" (whichever was the top command) --- it was a command I did a lot and it was almost gestural, kind of lke a well-done pie menu.

FWIW, the current Windows Start menu at lower-left, while not drawn to the corner now allows one to click the corner to open it, lower-right is "Show Desktop" and upper right closes the current maximized window --- only upper left is at the mercy of whatever app is currently running.
