Jane - I apologize if this isn't the place to bring it up, but this topic is related to a big issue for me with ingredient indexing.
Basically: The 30-item limit on dropdown lists makes it impossible to review the possible types of ingredients with large numbers of variants. Suppose a recipe calls for a type of sausage that doesn't seem to be in the ingredient list. You need to be able to review all the EYB types of sausage to see if there's one that is an equivalent. But '[space] sausage' brings up a list that only gets to L. Indexers can't be expect to guess the M-Z choices. The 30-item limit has to be increased, at a minimum.
Ideally, frequent indexers* have to be given (read-only) access to the full database, including the linked ingredients.
* EYB pro indexers, and members who've indexed multiple books (tiny % of members overall, and even pretty small fraction of members who've done any indexing).
