I don’t generally find desktop widgets on the Mac desktop to be useful; the desktop for me is a small collection of things I’m working on or about to file. But I did cobble these quick and easy Shortcuts, put them in a collection in the Shortcuts app, and display them on my Mac’s desktop for quick access.
One cool Shortcuts feature I never knew about is that they show up (and run) in both Spotlight and Launchbar. So you can really keep your fingers on the keyboard and get to what you need in OmniFocus, no matter what app you’re working in.
