+### Modern Developer SQL Editor (New in v0.17)
+Next-generation SQL editing ergonomics tailored for developer velocity and precision:
+- **IntelliSense 2.0 & Contextual Autocomplete**:
+  - **Contextual Table Alias Resolution**: Automatically maps aliases across single or multi-table queries (e.g., `FROM users u, orders o` or `FROM users u JOIN orders o ON ...`). Typing `u.` instantly suggests columns belonging specifically to the `users` table.
+  - **Automated Foreign Key Join Suggestions**: When writing `JOIN ... ON` clauses, relational foreign key conditions are detected from table metadata and surfaced at the very top of autocomplete suggestions (e.g., `orders.user_id = users.id`).
+  - **User-Configurable Keyword Casing**: Supports `UPPERCASE` (`SELECT`, `WHERE`), `lowercase` (`select`, `where`), or `Preserve` according to editor preferences.
+  - **Visual Completion Iconography**: Distinct category icons for quick identification (⚡ Keywords, 📦 Tables, 🏷️ Columns, 🧩 Functions, 📄 Snippets, 🔧 Parameters).
+- **Smart Statement Boundary Parser & Cursor Execution**:
+  - **Execute Current Statement (`Ctrl+Enter` / `Cmd+Enter`)**: Runs only the statement enclosing the cursor without requiring manual text selection.
+  - **Literal & Comment-Safe Parser**: Built with a dedicated state-machine (`src/query_tools/statement_parser.rs`) that safely ignores semicolons (`;`) inside string literals (`'...'`), quoted identifiers (`"..."`), line comments (`--`), and block comments (`/* ... */`).
+- **Ergonomic Shortcuts & Line Actions**:
+  - **Line & Block Comment Toggle (`Ctrl+/` / `Cmd+/`)**: Toggles `-- ` comments on cursor line or multi-line selections with exact indentation preservation.
+  - **Fast Query Formatting (`Ctrl+Shift+F` / `Cmd+Shift+F`)**: Instantly prettifies SQL queries with standardized indentation and active keyword casing.
+  - **Duplicate Lines (`Shift+Alt+Down`)**: Clones the current line or multi-line selection downward.
+  - **Move Lines (`Alt+Up` / `Alt+Down`)**: Moves the current line or selection up or down smoothly with cursor offset retention.
+  - **Active Line Highlighting**: Soft real-time background indicator on the currently focused editor line.
+- **Quick Result Exports to Clipboard**:
+  - 1-click export from the query results grid directly to the clipboard:
+    - 📋 **Markdown Table**: Clean GitHub-flavored markdown table with aligned column boundaries.
+    - 📋 **JSON Array**: Structured JSON array of row objects (`[{"column": "value"}, ...]`).
+    - 📋 **CSV**: RFC 4180 compliant CSV format with safe double-quote escaping.
+    - 📋 **SQL INSERT Statements**: Ready-to-run `INSERT INTO <table> (...) VALUES (...)` statements.
+
