It's not the same, though.

A widget is a thing that runs. It's an active process with a channel to create its own on-screen display, and the mere existence of it consumes non-zero CPU even if never invoked.

A shortcut is more like an icon on a Windows desktop, or perhaps a unix symlink. If it is never used, then it never really does anything at all.

Anyhow, Octopi. It does support shortcuts, but it seems like there's two different pathways for them and they do not work the same at all.

One pathway: Long-press the wallpaper and there's a list of them a tap or two away for some apps and it's easy to add them to the home screen. Home Assistant is in this list, but Shazam is not.

The other pathway: Long-press an app icon and a list of named shortcuts may appear. These are impossible to link to a home screen icon. And the per-app behavior is opposite: Long-pressing Home Assistant does not present this list, while long-pressing Shazam does.
