This is what I have understood:
Adding a field to a template makes the field 'available' to the template file. Which can then be echo'ed out (Ex: echo $page->summary), if it needs to be..Are there any cases where fields aren't echo'ed ? Just wondering..
Secondly it seems drag and drop on the fields on Edit Template is just for visual purpose, i.e it doesn't actually do anything. Right ? Not saying that it should, just I expected something on the page to change on using drag and drop and got a lil confused..
Please correct me where I am wrong.
Thanks
