Bumping for topic visibility.
Any minor or major component refactor is freaking scary if there are hundreds of instances, across multiple files, depending on it. In my experience, this is quite a common scenario.
Native searching for names is very limited, we often rename instances to better reflect their role as nested instances.
just to mention a super simple example: imagine a button with 2 placeholder icons, the same placeholder icon is used for both leading and trailing icons, and those instances need to be renamed to reflect their respective roles.
Using Figma native search we would never find that icon/arrow-left and icon/arrow-right are being used in example button instances.
