This version of Orion adds support for Safari extensions.
Vimlike is similar to extensions like Vimari, but more modern and cross platform (iOS/iPadOS/macOS).
I selected the existing extension (which is working fine in Safari) from my 'Applications' folder - there was a dialog box explaining the extension's access requirements and the install appeared to go correct.
All the preferences are available and I can activate/deactivate it without error.
But none of the keystrokes that would normally work (such as j/k to move through the document, and 'f' to select links) do anything.
