gnoviawan/termul — reverse-engineered prompt

Build me a modern desktop app called Termul Manager for developers who want one place to manage project work. It should feel like a polished terminal workspace app, not just a plain terminal.

Users should be able to create project based workspaces, open multiple terminal tabs, split the screen into resizable panes, and choose different shells like PowerShell, CMD, Git Bash, WSL, zsh, or fish when available. The app should remember workspace state so people can come back later and continue.

Include a file explorer with basic file actions, a built in code editor, a markdown editor with live preview, Mermaid diagram rendering, and embedded browser tabs so users don’t need to switch apps. Add a command palette, searchable command history, keyboard shortcuts, git status in the UI, settings for themes and terminal preferences, and friendly error handling.

Make it cross platform for Windows, macOS, and Linux using Tauri, React, and TypeScript. Look up current docs online if you need to.
