Proposal: Dedicated Button for Multi-Level Directory Preview & Navigation

[阳熙来]

Hello,

My apologies for creating a new conversation. I just want to ensure this message reaches you (the previous one may not have gone through properly, possibly due to my misuse of the Google Groups reply function).

Original thread: https://groups.google.com/g/onecommander/c/fzf_GQYGWVo/m/_ntOimWrAAAJ

The core benefit I was aiming for is the ability to preview (and then potentially navigate)  the hierarchy of other branches in the directory tree without navigating away from the current view. 

With your feedback in mind, I've sketched out a new idea that avoids the display-duplication problem entirely. Inspired by the "Expand to open folder" behavior in File Explorer's navigation pane, perhaps a dedicated button could be added. In the mock-up below, I've placed it just to the left of the sorting options, which would open a view for rapid multi-level preview and navigation. This would keep the UI clean while still delivering the powerful navigation enhancement. 

Thank you for your consideration!
