CollabShell v1.0.0 — Initial Release

Welcome to the initial launch of CollabShell, an independent, premium client application designed to manage, monitor, and run Google Colab cloud environments directly from your mobile device. Built using the Flet framework with the Flutter engine and Python, CollabShell provides a beautiful, responsive, and native client interface wrapping the Google Colab CLI.

Core Features

1. Session Lifecycle & Accelerator Control

• Accelerator Selection — Provision GPU tiers (T4 on the free tier; L4, G4, A100, H100 on Pro/Pro+) or TPU models (v5e1, v6e1) to handle deep learning, AI inference, and high-performance computing.
• Kernel Management — Start new instances with custom names, check active runtime statuses, restart python kernels to clear variables, and stop/terminate instances to release compute quota.
• Active Keep-Alive Daemon — Enable active background pings every 60 seconds to prevent Google from shutting down your VM due to idle timeouts.
• Auto-Cleanup — Configure session termination on app disconnect to preserve compute credits, or keep them active when the app closes.

2. Interactive Notebook Cell Editor

• Jupyter-Style Cells — Add, edit, delete, and re-order Code and Markdown cells.
• Rich Output Console — Parse colorized ANSI logs, output streams, execution traces, and view inline generated images (e.g. Matplotlib charts).
• Interactive Stdin Inputs — Support for interactive code prompts through clean pop-up dialog overlays when the remote kernel demands user input.
• Google Cloud & Drive Integration — Mount your personal Google Drive filesystem directly to the VM path (/content/drive) or propagate credentials (GCP authentication) with one click.
• Import / Export IPYNB — Load local .ipynb files to parse cell lists, and export your notebook progress back to standard Jupyter Notebook format.

3. Standalone Quick Run

• One-Shot Script Run — Execute local .py scripts on temporary Colab VMs without writing code in the cell editor.
• Script Customization — Pass custom command-line arguments to your scripts, specify execution timeouts, and choose to terminate or persist the VM afterward.
• Live Output Stream — View output streams and logs in real-time as your python script compiles and runs.

4. Remote File Browser

• Virtual Directory Navigation — Navigate the remote Linux filesystem of your Google Colab instance.
• File Transfers — Upload local datasets and scripts from your mobile storage, download remote output assets to your local device Downloads folder, and delete files on the instance.

5. Chronological Event Logging & History

• Event Trace Logs — Keep an audit trail of session creations, script executions, file transfers, and system automations.
• Filters & Search — Filter event lists by type (executions, file operations, state transitions) or session name.
• Export System Logs — Export history tables as .ipynb, .md, .jsonl, or .txt formats.

UI & Polish

• Solarized Branding Palette — Custom Solarized and dark-mode designs with Outfit typography and RobotoMono monospace console text.
• Swipe Onboarding Guide — Modern 3-step gesture onboarding introducing core features and handling permissions.
• Responsive Layout — Responsive screen design adapts smoothly from compact mobile viewports to widescreen tablets.
• Interstitial Ads — Built-in Google AdMob integration to support compute operations.

Performance & Security

• Multi-threaded Async Architecture — Heavy CLI operations run non-blockingly via Python's asyncio.to_thread engine, ensuring the user interface remains smooth and interactive even during long remote VM assignments.
• Mobile Forge Binary Compatibility — Recompiled native wheels (tornado, pyarrow) dynamically loaded from Flet's mobile forge to run the gRPC and websocket client bindings directly on Android.
• Privacy-First Sovereignty — All network connections go directly to Google Cloud without middleman proxies, and authentication tokens are kept secure in local sandbox directories.
