I had it in the initial UI, but then dropped it. There's some trade off here:
if we make it too prominent in the UI, I guarantee inexperienced users will
take current snapshot to mean 'all my current disk activity is being recorded
in the current snapshot', which isn't correct and could lead to potential data
loss if they revert (and ignore the explicit warnings virt-manager will show
before revert). But maybe some different wording will make it less ambiguous.
I should play with the vmware UI...
