I want edit fields in shipping methods in backend in magento but I can not find where are fields, I used template path hints but I can not find, how can I find forms elements in backend in magento?
Magento system configuration fields are generated from system.xml.
We can create system.xml file for each module, but we need to place that in
app/code/local/namespace/module/etc/
