Sync with Library scans your file looking for components that could be replaced by library ones. It will help keep files clean, and relink components that got disconnected from the library, or that got imported from Sketch and are not tied to a library.
Sync with Library scans your library and your file looking for components with the same name, and allows to decide which of them should be synced (local components will be replaced by the library ones).
It may also be very useful for re-linking components that for some reason got disconnected from the library.
As a specific case of re-linking, it may be very handy when importing libraries and files from Sketch into Figma, as components are duplicated in the local file and not automatically linked to the library. Sync with Library may be helpful to re-link them again and remove the local ones.

This first version of the plugin considers components only. Colors, Styles, Text styles, and Effects are not supported (yet).
