When working with a big document, there are many operations that take a very long time. For example, generating a TOC, deleting pages that cause text to reflow, etc. Tasks that happen almost instantly with reasonably sized documents can take many minutes when we get into 500+ pgs.

Currently we only see a spinning beachball (mac) when we get stuck in a long task. There's no way to determine whether it's just going to take a long time, or if indesign is completely locked up. The system sees it as "application not responding," but a lot of times patience pays off and eventually it finishes successfully.

Would be really nice if we could get a progress bar and a cancel button that appears whenever a task is taking longer than say 20 seconds or so.
