Hello, thanks for the suggestions.
@Iyanga: sure, something like this will work, but the problem is each item displayed in the two list boxes will also have at least one anchor, so not that much difference. But I have to admit, it would also look good that way, maybe I change the Layout to this one as I do really like it
@Bl!nk: sure, I already have a beta right click function to create rules based on the clicked item, but the problem here is, you can not specify up front which ingredients you want to keep and which not - thus I initially implemented the list. But you're right - this would work as well. Maybe I should make a poll how it should be displayed and how the ingredients shall be selected.
