When setting up data source connections, especially for CData connections, there may be a large amount of settings. There is currently an index which really helps to jump down to the setting you want to change.
This would be even better if the index floated on the left, so that you don't have to scroll up many pages. Similarly if you have changed a setting and want to apply it, you need to scroll all the way down to the Save button. If this floated at the top-right, this would be much easier to do.
