Option to Reject or Confirm New Connection When One is Already Active

[padreserwer]

When a remote session is already active, block or confirm any new incoming connection attempts.

Suggested Implementation Options:
Option 1: "Reject new connection if already connected"

If a user is already remotely connected to the host, any new incoming connection is automatically rejected.
Useful in scenarios where the machine should only be accessible by one technician/user at a time.

Option 2: "Show confirmation dialog when new connection attempts are made during active session"

When a second person tries to connect while a session is active, the host sees a popup with Accept/Reject buttons.
Optional timeout: auto-reject after 30 seconds if no response.

Why this is useful:
Prevents session hijacking or accidental multiple connections.
Increases privacy and control for the person at the remote machine.
Ideal for shared IT tools, corporate environments, or support desks where only one support agent should be active per session.

Optional Setting:
Add it as a checkbox in the client GUI :)
[x] Reject new connections when already connected
[x] Ask for confirmation when a second connection is requested
