I got tired and frustrated trying to get various templates to
work upon adding books and discovered that once I learned REGEX (I already knew basic HTML from the 3.x days), That I could cast an eye on the code and fix many (perceived

) problems in less than a minute (I have made a collection of saved searches and snippets).
Since I now only do 1 or 2 books at after a shopping time

, I find the GUI based workflow satisfactory.
As Always YMMV
