Setting to automatically update links on Open
Allow an option/setting to disable the dialog when opening a document with updated links and if a link has been updated it updates or doesn't update it automatically based upon the User Setting.
No Steve checking those boxes doesn't auto update links on an already open document
I'd love this feature too.
1) uncheck the first two checkboxes here: Preferences > File Handling > Links and create a keyboard shortcut to update links manually.
2) If you have a lot of documents and wish to update links, you could use Peter Kahrel's famous script "Batch Convert". In the Misc section check "Update modified links before exporting" and "Save changed documents on closing". Use IDML or anything else as target format. It doesn't really matter—all we want the script to do is open, update and save the source files.
There is already a Setting but i can only tell you in german.
It should be: Preferences > File Handling > Links > First two checkboxes.
