Dashboard had an antecedent called Konfabulator. Then, as often happens, Apple saw how popular Konfabulator was, and decided to do their own take on it - and that's when Dashboard came about... of course, that killed Konfabulator. And now that Konfabulator is long dead and buried, Apple decides to kill Dashboard.
What depresses me about new versions of apps or operating systems is when they go back in functionality and usefulness. Basically, the new version is a downgrade. It's extremely stupid. That's not progress, it's devolvement.
Apple has done that pretty often, and now with Catalina, killing Dashboard is a massive downgrade. I frequently ask myself why doesn't somebody over there research (1) what are people using a given feature for (2) if we take away that feature, can our new version substitute with something that's AT LEAST as good, if not better? I think there should be a rule "don't kill a functionality unless your new version is BETTER".
Nothing has changed for me since I wrote those posts some 3 years ago in this thread. I still use Dashboard daily. It is still massively superior to Notification Center. We all knew one day this was going to happen, so from time to time I'd try to force myself to use NC instead - and I just can't because NC is garbage.
Apple have lost their minds. Hey, maybe Konfabulator or something like that can come back and give us a Dashboard-like experience. So sad when Apple kills a great feature that people use every single day, and now the poor user has to hunt around for substitutions.
And sadly, it's an Apple tradition. I always marvel when they revise the subpar Finder, and in revising and upgrading they make sure that at least one thing is made worse. It's like a war on the users. SMH.
