Feature description
🧠User story: As a power user, I want two panes side‑by‑side so that I can copy/move files faster without switching folders.
😵💫Problem: Single‑pane navigation makes cross‑folder operations slow on large storages.
💡Proposal: Add a Split View toggle that shows two independent folder panes with drag & drop between them.
✨Acceptance criteria: Toolbar toggle to enable/disable split view.
Drag items between panes with visual feedback; choose Copy or Move.
Remember last location for each pane across sessions.
🤍🤝Notes/Tech hints: Implement as two RecyclerView fragments; ItemTouchHelper for drag; confirm operation when dropping.
Respect existing privacy switches for thumbnails/previews.
Why do you want this feature?
Faster offline management of large folders; aligns with privacy‑first and no‑internet defaults.
Additional information
Optional “sync scroll” when both panes show same tree, default off.
