Here is one great feature:
Create a form and include multiple Upload File Buttons on it. Next, click on each of these buttons and then go to the Properties Tab. You can now set the maximum file upload size for each individual button. Yeah that is cool
Give your form a test and look at the form results in the Dashboard. All file attachments you can access directly through your S-Drive account.
This has been one of most requested features to add to the Flash version. So now that you have it, what do you think?
