Control Center
A grouped machine list with live host CPU and memory, and per-machine figures at a glance.

Why it matters
The question you actually have when several machines exist is which ones are running and what they are costing the host. That should be the first screen, not a menu item.
What changes
Without it
- Open each machine to find out what it is doing.
- Check Activity Monitor to see what the host has left.
With 1VMTool
- One list, grouped by state, with live host metering above it.
What it covers
- Machines grouped by running state
- Live host CPU and memory meters
- Per-machine CPU, memory and address at a glance
- Start, stop and open a console from the list
What you get out of it
- See the whole picture without opening anything
- Notice host pressure before it becomes a problem

Every screen states its limits before you commit to anything.
