A Real Tragedy
The omission of the dashboard and the elimination of widgets is, in my view, a real tragedy. I've read a number of posts contending that it is no big deal; I disagree. In my dashboard, I had:
• Weather widgets (6 of them) for places that friends, family or colleagues were
• Clock widgets so I didn't call them at inappropriate times
• 2 calculators (one left on 'basic'; the other in 'scientific' mode)
• Countdown timers for up to four project events
• Dictionary
• Thesaurus
• An excellent unit converter (this one really hurts as I can find no really good unit converter for the notification center)
• Language translation widget
• Webserver control widget
• Checkbook entry widget
• Calendar event entry widget
• and more.
Many of the widgets were better than anything currently offered for the notification center. The current weather tool shows you the weather for up to 6 hours (instead of the old one's 24) and forecasts for the next 5 days instead of 10. The only unit converter I can find (Euler) knows nothing about centimeters or millimeters, much less that bountiful number of other unit conversions that the Unit Converter offered. And the vast majority of the other useful Dashboard widgets aren't even available in Notifications versions.
And all were accessible with one keystroke. No need to open apps, no need to use desktop space; all of them at my fingertips in less than a second, easy to use and gone in another keystroke. There are those who argue that items in the Finder's menubar can replace this functioanlity; with respect, I disagree. Including system items like the clock, Time Machine, Sound, Bluetooth, etc., I have 20 such items in my menubar now; they are a pain to mouse to, you have to treat each one differently and every now and then one or more of them disappear, since the menubar was never intended to house that many.
It's a real shame that Apple decided to pull this functionality; the dashboard and its widgets used almost nothing in the way of system resources and provided serious functionality for those who cared to use it.
