The dropdown in the Security tab lists all compatible data sources in the application (which can be more than one). We don't plan to change that as it would require rendering different UI for this case. Not to mention that Security is rarely configured more than once per application.
When will the issues with the cursor not changing from an arrow to a wait cursor and the Finish button click exception be addressed?
For small projects, it may not be a big deal. But, for projects with lots of tables, it is really noticeable and frustrating.
Additionally, the Finish button needs to be disabled immediately after it is clicked. If it is clicked, while it is processing, it raises an exception. So, this is a bug that needs to be fixed either way.
