Apple finally kills vestigial Dashboard in macOS Catalina
After digging around in the first macOS 10.15 Catalina beta, one thing has become abundantly clear -- Dashboard is officially getting phased out in favor of Notification Center.

An icon for Dashboard, carried over from a previous Mac configuration, is not accessible in Apple's first macOS Catalina beta build.
Dashboard was first introduced in OS X 10.4 Tiger and acted as a dedicated hub for widgets, such as weather, calculator, timer and third-party software.
As user interest waned, however, Dashboard was disabled by default in OS X 10.10 Yosemite, to be replaced by Notification Center. It continues to be disabled in macOS 10.14 Mojave, requiring users to enable the feature manually if they wish to use it.
In macOS Catalina, Dashboard is entirely absent. It cannot be enabled via Mission Control and code for the feature appears to be scrubbed from the operating system betas released to developers on Monday. In Launchpad, Dashboard's icon is literally a large question mark, similar to iTunes which will soon be replaced by standalone Apple Music, Apple Podcasts and Apple TV apps.
Appleosophy attempted to use Terminal to force Dashboard to disable and enable. Typically, this action would bring back an inactive dashboard, but it did not. Dashboard was still missing regardless of the forced reboot.
With Dashboard not long for this world, users relying on the hub for bite-sized applets will need to accustom themselves with Mac's Notification Center. The feature's Today view assimilated most of Dashboard's functionality, including the ability to install third-party widgets.

Dashboard is still used by many people, including me. Yes, it was severely neglected by Apple, which was its only flaw.
It will be missed, mostly for its nostalgic meaning.
That was extremely useful. Really going to miss that.
Of course I still pine away for SeeUSeeMe and the guy who pointed his camera out his window towards the NY Thruway back in the mid 90s. Nothing like the 8-bit greyscale rendition of headlights at night!
It was all fun but I don't miss it and routinely turn off Dashboard for people.
At one point I had developed a custom RSS widget for a forum I once hosted, but it was rarely used and so I stopped supporting it.
I use it daily with 6 widgets on my board and will absolutely miss it but I also agree with their headline. That macOS feature has been holding on year-after-year without any updates that I'm surprised that it was killed off years ago.
Maybe someone will be able to create a 3rd-party service to bering it back, but If Hot Corners also goes away I'll seriously have to reconsider how I use macOS.

I kinda joke about it, but it's literally one of those legacy apps I use ALL THE TIME and every year I quickly check to find out if it's been axed. I figured the 64bit version meant it was here to stay.
This makes me sad. STEVE JOBS WOULD'VE——never mind.
Weather is in your Notification Center.
Conversion you can do with Spotlight — just hit cmd-space and type "3 cups".
Timer you can ask Siri.
as for the hex color thing, not sure what you were doing but check out Sip in the App Store. It's awesome!
