Using Hook 2.2.1 (script version 1.55), DevonThink Pro 3.6.1, Big Sur.
In DevonThink - within a group of a database, I selected a range of files and dragged them to the menubar Hook icon and after dropping them on the window I get a message that the items are hooked together.
But when I select a file within DevonThink and invoke the Hook Shortcut (⇧+ ⌘ + Spacebar) the other hooked files are not shown.
In Finder if I invoke Hook for the selected file the other hooked files are shown.
I have recorded a secret movie which to show this - see the video
Is this a limitation of using DevonThink?
