- refactoring (extracting functions and variables, renaming across entire project etc.)
- context aware selection (expand selection from cursor logically)
- stack trace / error parsing
- comparing anything (diff selection with clipboard for example)
- DB schema support even in SQL formatted as strings (e.g. when using psycopg) directly from DB by just connecting to a DB
- find in files (I've never seen a VS code user have an easy time finding stuff)
Etc.
