Refresh data source
I think it would be useful to have an ability to quickly re-read a data source using some kind of button in the ribbon. For example, if I have an XML data source and its structure is changing while I'm working on a report, I have to go to the Data Sources, click Edit, Test, OK.
While in the AutoTag Data Bin it would be useful to be able to right-click on a node (table, view, etc.) and press "Refresh" to re-read the columns of the table or view, etc. Currently, one needs to go to edit the data source in order to do this which is inefficient.
