Often content I want to paste into a Grid from an outside source already has an outline structure of some kind, but it's not tab-indented.  And so when I paste it into an IQ grid, the hierarchy that was present in the outside source is not replicated as a parents/children outline in the Grid.   The content as pasted as items all at the same level.  So if I want to reproduce the hierarchy in a Grid outline, I have to go through all the items and indent each one to the appropriate level.

Just as example, I used the Copy icon in Copilot to copy a Copilot response to the clipboard, which I discovered is in Markdown format.  If I paste such content in the Doc pane using Right-click > Paste Special > HTML Format, IQ generates HTML headings corresponding to the headings in the Markdown.  So pasting in HTML format in the Doc pane preserves or replicates the original hierarchical structure that was in the Markdown text.  But if I paste the same Markdown content in the Grid, this hierarchy is not preserved:

Ideally, the structure in the original source of the pasted content would be replicated in the Grid.  Of course, I'm sure that different external sources represent hierarchical content in different ways and it wouldn't be easy for IQ to detect and replicate them.  Just an idea for sometime in the future.
