two-step 'disconnect' option with custom message

[tlcarpenter]

Is your feature request related to a problem? Please describe.
The request is related to a security issue I submitted to Apple. I'm wondering if there is a way to communicate privately via email, if necessary, about the issue.

Describe the solution you'd like
An option to display a custom message when noVNC's 'disconnect' button is clicked; the message would be displayed prior to noVNC actually being disconnected and would give the user the option to cancel the 'disconnect' action or to proceed with disconnecting.

Describe alternatives you've considered
Not aware of any.

You'd like a confirmation popup when disconnecting? Why would this have to be custom? And what does it have to do with Apple?

[samhed]

I got the following response outside of github:

The custom aspect of what I'm requesting is just to have the ability to
specify the text of the notification in the popup; in my case I'd like
to say something like "Have you logged out of your account on the remote
system? Terminating the VNC connection without logging out of the remote
system may allow access to the remote system's console if you reconnect."

I'm not so sure about the ability to customize this. But a general message could be interesting.

One issue though is how to hide it for users that understand how this works. E.g. a "Don't show this again" check box. We don't currently have any mechanism for that.

[samhed]

Couldn't such a "don't show this again"-choice be saved alongside the rest of the UI settings in the web storage?

[CendioOssman]

Yes, sorry. I got this confused with TigerVNC where we don't have as flexible storage. :)

In the same line, could be added an option to send some key combination to logout the remote user then you click "disconnect" being those key combinations configurable in the parameters, for example for windows & ubuntu (windows + L) to lock the user or (Ctrl+Alt+Del) to logout in ubuntu
