New in 5.0: Support for Archived Setups

This is a new feature I've been wanting to blog about for a while. It was inspired by a request from a customer who wanted to be able to store the different configurations of web forms and be able to later reuse them. For example, at some point there could be a form for "Contact Us", another for "Request for detailed information", another for "Inscription for event X", etc. Not all of these forms would be active at all times so it was needed to be able to hide the portlet but keep the configuration available for future occasions. Also some form configuration

This was clearly a feature that many people could benefit from so it would fit into the product itself. Furthermore we realized that the idea could be useful to several other portlets such as navigation, asset publisher, etc. So welcome to "Archived Setups". This feature is available  through a new tab called "Archived Setups" within the configuration UI as shown in the following screenshot:

Within that tab you can save the current setup by giving it a name or restore any of the previously archived setups:

The archived setups are community wide and are included in the LAR files when exporting or exporting either the whole community or the data of an specific portlet. Access to this functionality can be controlled through the permission system by giving or removing from users the  "Manage Archived Setups"  permission. By default only the community administrators have access to it.
