As #22 was fixed, it seems that the "Check connection" also works as a Save button now, even for the changes done under the Show Advanced Configuration section.
As the ticket also had "We should add an option to save the settings on the same section (e.g. add a "Save connection" button" next to "Check connection")" a clarification needs to be made on what exactly dose the "Check connection" button dose, and make it obvious for the users.
