Fear no more - we're not protecting you by confirming page navigations if there are pending changes that were not yet saved. If you make a change to a transcript, or modify something in the synchronization page and try to navigate to another page, you'll get the following warning:
You have pending changes. Are you sure you want to leave this page and loose changes?
Hope you'll never loose a change again :-)
Note: For the technical savvy, this is implemented using the onbeforeunload event, which is quite simple. I should have added it a long time ago.
