A discussion in a recent thread has led me to believe that the FTM Dashboard widget has morphed into uselessness, because Dashboard, for which it was built, no longer exists. (Nor, for that matter does /Library/Widgets, where it lived, exist any longer.)

Should the offer be taken down?

Speaking only for myself, there are still a significant number of users on FineTunedMac who are using older macOS versions that can use the FTM Dashboard Widget so I would say leave it up.

Oops! You're of course correct.
