I can’t believe how difficult it is to modify the admin interface so that when you are adding an item, that in the Design menu options, it would default to “Product Info Column” rather than “Block After Info Column”. After hours of searching, I came up with a hack, it’s not the best fix, but it works for my scenario in which I would never set the options to use the “Block After Info Column”. Personally, I think that “block after info column” design is poor usability, so it baffles me what that is even the default.

Anyways, the way I got around to fixing this is to simply remove that option as a possible selection option in the dropdown, so that is left is “Product Info Column”. So if this is something that suits your need, all you would have to do is the following:

Modify config.xml inside: app/code/core/Mage/Catalog/etc, and go to line (approx): 257 and look for the xml block:

<option2 translate=”label”>
<value>container2</value>
<label>Block after Info Column</label>
</option2>

Hope this helps!!
