I wish Apple would bring back the Dashboard for modern macOS versions, using the modern widget technology. I like the modern widgets but it's awkward that you can only use them on the desktop or notification centre. It's been gone for years now, but I still really miss Dashboard!
What I'd like is:
* Dashboard is a special desktop that appears to the left of the main desktop
* Can be accessed with a single F-key press, or by swiping with the trackpad/Magic Mouse
* Widgets can be organised/laid out any way you like, anywhere on the screen
I'm not sure what it was called but the "web clipping" Widget was always my favorite. It worked really well to just have a always updated time table from your school in the dashboard just by basically taking a screenshot of it once.
There was also an overlay option to see Dash atop of other apps, which I liked more than the extra desktop. You could pop up a unit converter without “leaving” the current program/desktop.
It was an absolutely brilliant idea, which they tossed... But .. nothing prevents someone from retro programming it or a better one.
Apple has left behind some of the most brilliant UX/UI ideas of the century...
