Smarter Hints

Duplicate code detection works even when variable names differ.

Each folder can have its own formatting configuration (see EditorConfig at https://editorconfig.org).
Cursor Word‑Movement Configuration
You can configure how the cursor moves to the next word.
Tab Smart Shortcuts
When writing code, pressing Tab can jump out of quotes or parentheses.
