Branching snapshot tree
Real branching history with tree glyphs and per-node unique data, so you can see where a machine diverged and what each branch costs on disk.

Why it matters
A flat list of snapshots stops being useful the moment you restore an old one and carry on working, because the history is no longer a line. Most tools either hide the branch or flatten it. Seeing the real shape is what lets you navigate it.
What changes
Without it
- Snapshots are a flat list, and restoring an old one quietly orphans the newer ones.
- No indication of what any given snapshot is actually costing you.
With 1VMTool
- The tree shows branches as branches, drawn with tree glyphs.
- Each node reports its own unique data, so the expensive branch is visible.
What it covers
- Branching history with a real tree view
- Per-node unique data figures
- Restore from any node
- Named snapshots with timestamps and state labels
What you get out of it
- Understand a machine's history rather than guessing at it
- Find and remove the branch that is actually consuming space
- Move between experiments without losing either one
