The model properties screen allows you to configure the models in your deck.
Name
This setting allows you to rename the model. The model’s name also functions as one or more space-separated tags. Thus if you call your model "Japanese Revision", you would be able to find that model by searching for the tag "Japanese", or the tag "Revision".
Some plugins will only operate on certain models. For example, language-specific plugins often require that your model has the language name in it.

Card Templates
Options related to the model’s card templates.
Disabling a card template will prevent cards from being created in the future when you add more material. It does not affect existing cards.
Changing the order of card templates alters the order new cards will appear in.
Most of the configuration of card templates is done via the card layout screen.
