Align-self

Using auto-layout in design is common and reasonable nowadays. This tool is to help you make some of the elements in an auto-layout frame align differently. Why so? Think about there's a form, all inputs are left-aligned, but you want the button on the bottom right-aligned, you have to manually add a frame outside the button and move the button to the right.

It's called align-self in CSS, but it's missing in Figma, so I added it.
