There are use cases, such as the [expense tracker app](https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/qs_aotp_app_step2_cmp.htm) in the *Lightning Components Developer's Guide*, where users are entering data into a dynamic list that grows with each user input submission. My question is, in these situations, what is the most efficient way to implement a UI element that allows the user to *remove* an item from the list?
