+  - Model 2 (24 × 80)
-- **OIA Status Line**: Real-time Operator Information Area displaying connection state, keyboard lock, insert mode, cursor row/col, and LU name.
+  - Model 3 (32 × 80)
-- **Host Profile Storage**: Save and manage multiple mainframe connection profiles with custom ports, models, and SSL/TLS options.
+  - Model 4 (43 × 80)
-- **Background Session Persistence**: Android foreground service keeps your terminal session alive when multitasking.
+  - Model 5 (27 × 132)
-- **Terminal Models**:
+  - **Dynamic Screen Dimensions**: Configurable custom geometry (rows & columns up to 255 × 255).
-  - Model 2 (24x80)
+- **EBCDIC Code Pages**: Full character translation across international code pages (037, 1047, 500, etc.).
-  - Model 3 (32x80)
+
-  - Model 4 (43x80)
+### 📊 Graphics & Peripherals
-  - Model 5 (27x132)
+- **GDDM & GOCA Graphics**: Native rendering of Programmed Symbols (PS) and GOCA vector graphics directly in the Compose canvas.
+- **Light Pen Simulation**: Interactive touch support to simulate light pen selection and graphic cursor pick correlation.
+- **IBM 3287 Printer Emulation**: Integrated printer session support for spool/report capture (via associated display LU or dedicated printer LU) with direct printing through Android PrintManager (PDF export / system print).
+
+### 📁 IND$FILE File Transfer
+- Full mobile UI supporting both **CUT** and **DFT (DDM)** high-speed structured field transfers.
+- Compatible with **TSO**, **VM/CMS**, and **CICS** environments.
+- ASCII/binary translation, CRLF conversions, and configurable record format (`recfm`), record length (`lrecl`), and allocation units.
+
+### 🔍 Developer & Productivity Tools
+- **Field Inspector**: Live interactive inspector displaying start/end addresses, length, protection, numeric status, MDT (Modified Data Tag), display intensity, and extended highlighting/color, with one-tap "Jump to Field".
+- **Screen Search / Find**: On-screen text search with case sensitivity, forward/backward navigation, and visual match highlighting.
+- **Screen Exporter**: Export the current screen buffer to **Plain Text**, formatted **HTML**, or **PNG image**, with one-tap clipboard copy and Android system share sheet integration.
+- **Script & Macro Automation**: Built-in script runner supporting automated keystroke and wait sequences (e.g. `[enter]`, `[wait]`, `[tab]`) for login macros and repetitive tasks.
+
+### ✍️ Entry Assist & Typing Modes
+- **Document (DOC) Mode**: Configurable left/right margins, custom tab stops, and end-of-line bell warning.
+- **Word Wrap**: Automatic word wrapping across lines during input.
+- **APL Mode**: Support for APL extended character sets and symbols.
+- **Field Handling**: Automatic field skip (Auto-Skip), Numeric field lock, and Insert Mode auto-reset on AID transmission.
+
+### 🎨 Display, Themes & Ergonomics
+- **Jetpack Compose UI**: Smooth, hardware-accelerated 3270 terminal screen rendering with touch-to-position cursor.
+- **Color Themes**: Light and Dark application themes, 3270 extended color support, and 4-color legacy override mode.
+- **Cursor Customization**: Block and Underline cursor styles with toggleable blinking.
+- **Crosshair Ruler**: Toggleable horizontal and vertical ruler lines following the cursor for easy data tracking.
+- **Block Selection**: Rectangular text selection and copy mode.
+- **OIA Status Line**: Real-time Operator Information Area displaying connection status, keyboard lock, insert mode, cursor row/col, LU name, and inhibit reason codes.
+
+### 🔒 Security, Networking & Storage
+- **SSL / TLS Encryption**: Secure encrypted mainframe sessions with TLS certificate verification.
+- **Interactive Untrusted Certificate Prompt**: Inspect SSL certificates, view full certificate chain details, and accept/reject unverified connections.
+- **Proxy Support**: Connect via HTTP CONNECT, SOCKS4, SOCKS5, and Telnet proxies with optional user/password authentication.
+- **Background Session Persistence**: Android foreground service (`specialUse`) keeps your terminal TCP connection alive with status notifications when multitasking or screen is off.
+- **Host Profile Manager & INI Export**: Save multiple mainframe profiles, configure auto-connect on launch, and export/import configuration in INI format (interoperable with desktop `j3270`).
+
+### ⌨️ Input & Keyboards
+- **On-Screen Function Key Bar**: Two-row responsive touch bar providing PF1–PF24, PA1–PA3, Enter, Clear, Reset, Attn, SysReq, Erase EOF, Erase Input, Tab, BackTab, and D-pad cursor controls with haptic feedback.
