auto save/preserve function for backend open documents function
The content of backend forms should be saved (with ajax) into the session in defined time intervalls.
This should be combined with the "Open Documents" function.
So if the users closes a form without saving by mistake, he can get the form back with the open document function and the entered data.
A lot of users have the problem that they loose their work from time to time, by closing the browser without saving or most common klicking to some other place within TYPO3 without thinking about the consequences.
If typo3 automatically saves the form content every minute to the user session and if the user klicks on open documents it reloads the preserved data, that would be a great solution.
This way has a big advantage of the normal auto save function, because the record is not saved itself. This prevents a lot of possible problems.
