While working in a LAN (2ms Ping) or WAN (20ms Ping) with linked content on exhouse Servers, InDesign is getting very very slow.
Reason is the permanent pinging to the linked files "R U still alive?" which the user cannot stop.

It would save hours of time and tons of nerves each week, if user could easily switch-on and switch-off the ping manually - e.g. like the preflight. While saving, printing or exporting the file the ping should be activated automatically, to inform the user about any changes.
