I find it somewhat unwieldy that when I want to change the query for one of my many SQL Server data sources, I have to go into the Reconfigure Connection screen. It would be much easier if the query were shown to the right of the connection information and had a test button and an update button. The test button would execute the query and verify that it got a valid tabular result back (I don't even care if it shows me any data, just whether the query was successful) and once I have used the test button and it has come back OK, then the update button will be enabled to allow me to update the query in the configuration. It can refresh the data at that moment, or queue it for refresh, or not, doesn't really matter to me. We need to add a new filter condition to most of our queries, and there are a few more steps per data source with the current setup than there would be...
