Hi Dmitry,

I've kept this thread in my VirtualBox inbox because I've always
wanted to revisit how VirtualBox handles Snapshots.  I believe there
is room for improvement and I'd like to present some ideas below.  

I welcome all VirtualBox users to comment because together, I think we
can come up with an excellent set of suggestions.

For this example, let's assume the following state of affairs:

    Snapshot 1
        +---> Snapshot 2
                  +---> Current State

and our VM is currently paused.

Summary of Changes
==================
For those folks who don't want to read all the details, here are
suggested menu label changes for Snapshots:

                           Menu Labels
         Current                            Suggested
----------------------------------     -----------------------------
Revert to Current Snapshot             Revert to Current State

Discard Current Snapshot and State     Discard Current State and the
                                       Previous Snapshot  

Discard Snapshot                       Merge Current State with the
                                       Previous Snapshot 

Use Case with Comments
======================
What I'd like to do is run through a scenario and provide the feedback
at distinct steps.

Use Case
--------
If I select 'Current State', I'm allowed three options:

   1) Revert to Current Snapshot
   2) Discard Current Snapshot and State
   3) Take Snapshot

If you select 1), it means any changes to the VM from when the
'Current State' was snapped, will be lost.  We revert to when the
Snapshot was taken.

Feedback
--------
I think the menu label 'Revert to Current Snapshot' should be changed
to

   Revert to Current State

Use Case (cont)
---------------
If you select 2) (Discard Current Snapshot and State), we end up with:

    Snapshot 1
        +---> Current State

Feedback
--------
I believe to match what's being displayed in the tree, it might make
sense to change 'Discard Current Snapshot and State' to:

   Discard Current State and the Previous Snapshot 

It's a subtle difference but it ties the menu item with the graphical
label.  Also, it works well with the next suggestion below.  (Or I
think it it does!  <g>).

Use Case (cont)
---------------
Re-create my previous environment, I have the following:

    Snapshot 1
        +---> Snapshot 2
                  +---> Current State

If I select 'Snapshot 2', I have one option:

   Discard Snapshot

When I select it, I end up with this:

    Snapshot 1
        +---> Current State (changed)

What's happened is the 'Current State' has been merged with
'Snapshot 2':  any changes made in 'Current State' are rolled into
'Snapshot 2', with the results creating a new 'Current State (changed).

Feedback
--------
I believe the option label needs to be re-written.  The label does not
reflect what happened.

I suggest the label be changed from 'Discard Snapshot' to:

   Merge Current State with Previous Snapshot
