Working on a site with several steps that have to be done by different editors. I am afraid of data loss through cross-editing (two or more users editing an entry at the same time).
The item should not be locked down completely, I would just like to have a warning displayed. This would prevent accidental lockdown (someone leaves their browser open while editing a post and goes to lunch).
This all has to happen on a Safecracker form.
There is one add-on on devotee, but the reviews say that it breaks Zoo Admin and the author seems to be unresponsive.
