Editor User Guide
Metadata is a set of key/value pairs that help describe your extension. Technically they have no impact on how your extension performs, but they can be read via the
context.meta object and used to alter behavior if you choose. To view metadata, click the wrench icon and select the Meta option.
Once metadata has been added, you can view each key/value pair and either edit or delete them. Note that you will not see a delete icon until you mouse over a particular metadata key/value.
