The fuel registry edit menu can be used to modify custom fuel registries or create new ones. If you just started creating a new fuel registry, it should look like this:

• The 'Cancel' button will take you back to the fuel registry overview, without keeping changed made to this fuel registry or creating a new one.
• If you are creating a new fuel registry, there will be a 'Create' button. Clicking it will add the fuel registry you're designing, and take you back to the fuel registry overview if it went well.
• If you are editing an existing fuel registry, there will be an 'Apply' button. Clicking it will take you back to the fuel registry overview and keep the changes you made to it.
• You need to type the name of the fuel registry in the text edit field on the right of 'Name:'. Currently, the name is not used in the plug-in; it's only purpose is to distinguis different fuel registries from each other.
• The most important part of a fuel registry is the list of entries. These actually determine which items are considered fuel. To change this list, click on the 'Entries...' button, which will take you to the fuel entries menu for this fuel registry.
