I have a basic question that which way of updating is good in local.xml or in every .xml files separately. I observed that for each update i have to go to my .xml files in base then copying tags then edit.
I already did a project editing .xml files separately from my local package/theme. It looks easy to me.
I want your suggestions as i am newbie
I followed the link for better way of layout update from local.xml as well:
