Import, export and restore points

The New button's menu in the snippet list has the doors in and out. Import from another text expander reads a CSV (a header row with an abbreviation and a body column, or plain two-column rows) and shows what it found before writing anything. Import Browser Extension reads a package the Mac app or another browser exported, and Import Template (.zip) reads a template pack. Export Package for Browser Extension writes your whole library as one file, which is also the backup that survives an uninstall.

A restore point is a copy of the library, taken before snippets are removed and every few hours otherwise. Settings → Snippets → Restore points lists them with what each would bring back, remove or change; Restore puts one back. They live in this browser only, so export a package for anything you would mind losing.
