I havn't looked very thoroughly through ALL the feature requests so not sure if this one's in there or not. Apologies if this is a duplicate
I would find it very useful to be able to search or filter by Source when looking for recipies. I use that field for putting the cookbook, website or cooking course where I got the recipe and often want to find "all recipes from the Mexican Cooking Class" or "all recipes from 'X' Book" for example. Ideally a filter button on the left hand menu (the same as for cuisine or main ingredient) but even an extra search field in the advanced search options would be good. I guess this would mean that field would have to be linked to a table rather than being free text as I think it is now so not sure how difficult that is but it would certainly make Big Oven about perfect for me (instead of 99% as it is now).
