Allow overriding existing snapshots

[Tobbi]

Currently, you can only specify a new snapshot from the Virtual Box VM menu. I think it would make sense if a window opens where you can select to override a snapshot, delete snapshots or create new ones.

Like if you select a VM and look at the top-right corner where it says "Details | Snapshots"?

Take a look at the User Manual, Chapter 1.10.1 "Taking, restoring and deleting snapshots".

The problem isn't actually restoring or deleting them. I'd much rather like to have an option to override an existing snapshot from the VM's menu.

I'm not sure if I understand your intention. Replacing a snapshot older than the latest created snapshot (e.g. snapshot '5') would only make sense if you go back to that snapshot (restore '5'), then run the VM and then create a new snapshot (e.g. snapshot '5a') plus discard the previous snapshot (discard '5'). A "Replace snapshot" operation would probably combine creating of the new snapshot and discarding of the other snapshot. A "replace snapshot" operation from the GUI would only make sense when applied to the latest snapshot. Your intention of such an operation is probably to have a convenient function which creates a snapshot of the most recent "working state", for example for backup reasons, without creating too many snapshots. Nevertheless such an operation would always first create a new snapshot and later discard the most recent snapshot.

But I think such a scenario (having one up-to-date snapshot of the know-to-be-working VM state) could make some sense.

Actually that's my modus operandi for all my VMs, so yeah, that idea I could support. I have one snapshot only per VM, to which I revert almost always. If I want a change permanently applied, I make the changes, take a second snapshot and delete the first.

Yes, it would make a lot of sense, but I'll leave it to the devs to figure out how many cans of worms it could open. Not in terms of implementation but of user-confusion.
