We would like some system where the properties which define a map can be saved and reloaded to be generated again later. This has the following benefits:

1. Effectively makes edits of previously made maps viable without entirely recreating
2. Allows comparisons between game versions to be made

Considerations:

1. Which features should be kept in the recipe, and which are considered user preference. For example the 'items to plot' is obviously a key part of the recipe, but what about icon size?
2. What happens if an item previously plotted in a recipe no longer exists in the database - we'd need to handle this gracefully
