I\'m having issues getting the customer.xml layout file to work properly for the customer\'s \"my account\" pages.
The navigation links and the previously ordered items
In response to dolu (for anyone else who has this problem), if you put Alan's module in app/code/community, you need to edit app/etc/modules/Alanstormdotcom_Layoutviewer.xml to use the "community" codePool. The module expects to be installed at app/code/local by default (at least the version linked to Alan's answer here).
