No keyboard shortcuts for iOS in Things 3? You'd think there would have been time to add those in the fourteen years that it took to develop this version.

The macOS version of Things has excellent keyboard support, but sadly none of it has made its way to iOS. There is not a single shortcut, which is difficult for me personally as an iPad-first user. It's surprising as well, since Things 2 at least had a handful of shortcuts on iPad.
