I think I understand what you want, but I don't understand why you would want it or what the term "linear" means in your post.

One thing to be aware of is that logical links are all equal (there is no notion of primary or secondary links). I am guessing that you want the first "instance" of an Info Item be primary (and always show in the Data Explorer Pane), and consider Logical Links as secondary (and only show in the Child Items Pane) which isn't how Ultra Recall works (correct me if I've misunderstood your suggestion).

Another issue that comes to mind in doing what you suggest is that logically linked Info Items can be parents of other Info Items (both singly and logically linked themselves)... If Logically Linked children weren't displayed in the Data Explorer and only the Child Items Pane, you would have to navigate or "drill down" in the Child Items Pane, but the Data Explorer would become "disconnected" because the Logically Linked parent of the displayed Info Items in the Child Items Pane wouldn't be displayed there.

I assume we are missing something about your post/suggestion because the whole concept of Logical Linking from our perspective was that multi-linked Info Items would show up in multiple places...

Please elaborate (perhaps with a diagram with some example data) to demonstrate exactly what you are proposing, why it is needed (and useful to a wide range of users) and enough implementation details to show it can be an intuitive feature...

To respond the second post in this thread, the default delete action is to remove the logical link (as you mentioned), and Ctrl+Shift+Delete will permanently delete all Logical Links of the selected Info Items, as requested.
