[Windows] Sidebar, home dashboard, command palette, settings, and secondary views

[2witstudios]

Overview

Implement all WPF views to reach full feature parity with the macOS app.

Sidebar (Views/SidebarView.xaml)

WPF TreeView with HierarchicalDataTemplate:

• Project → Worktrees → Agents/AgentGroups/Terminals
• Status dots (colored Ellipse bound to status converter)
• Navigation tabs: Dashboard, Swarms, Prompts, Schedules, Agent Config
• Context menus (right-click): Kill, Restart, Rename, Delete
• "+" button triggers SpawnDialog

Home Dashboard (Views/HomeDashboardView.xaml)

• ItemsControl with project cards
• Each card: project name, branch, worktree count, agent status dots
• Commit heatmap: WPF Canvas with Rectangle elements (13×7, 5 color levels)
• Recent commits list: ListView with hash, message, author, relative time
• Git data via Process.Start("git", "log ...") on background thread

Command Palette (Views/SpawnDialog.xaml)

• Modal overlay (borderless Window or Popup)
• Phase 1: TextBox search + ListBox of agent variants (filtered)
• Phase 2: Multi-line TextBox for prompt
• Keyboard-driven: arrows navigate, Enter selects/submits, Escape dismisses
• Triggers spawn via REST API

Settings (Views/SettingsView.xaml)

• TabControl with tabs: Connection, Terminal, Appearance, Shortcuts
• Connection: URL, token (PasswordBox), test connection button
• Terminal: font picker (monospace ComboBox), size (Slider 8-24), shell, history limit
• Appearance: System/Light/Dark radio buttons
• Shortcuts: DataGrid of bindable actions with key recorder
• Persist to %APPDATA%/PPG Desktop/settings.json

Split-Pane Grid

Same binary tree model as Linux issue #135:

• PaneSplitNode recursive enum (Leaf/Split)
• WPF Grid with GridSplitter for resize handles
• Max 6 panes, keyboard split (Ctrl+D / Ctrl+Shift+D), close (Ctrl+W)
• Focus tracking, hover overlay with split/close buttons
• Grid layout persisted in dashboard-sessions.json

Prompts View

• Grid split: ListBox (left) + TextBox editor (right)
• Lists .ppg/prompts/*.md and .ppg/templates/*.md
• Segmented filter
• Markdown-aware syntax highlighting (can use basic regex-based coloring via RichTextBox or custom TextBox adorner)

Swarms View

• Split: swarm list + form
• YAML parsing via YamlDotNet NuGet or manual parsing
• Create/edit/delete swarm definitions

Schedules View

• Calendar with Day/Week/Month modes
• Cron parser (port the macOS CronParser.swift to C#)
• Scheduled runs shown as colored blocks

Agent Config View

• 3 tabs: CLAUDE.md editor, Skills, config.yaml
• Full text editors with syntax highlighting

Session Persistence

• Match macOS DashboardSession.swift
• Persist entries + grid layouts to .ppg/dashboard-sessions.json
• Debounced writes, synchronous flush on exit
• Restore sessions on relaunch

Multi-Project Support

• List of ProjectContext persisted to app settings
• Sidebar shows all projects
• Ctrl+1-9 switches projects
• Each project has own manifest watcher + session

References

• macOS sidebar: PPG CLI/PPG CLI/SidebarViewController.swift
• macOS dashboard: PPG CLI/PPG CLI/HomeDashboardView.swift
• macOS palette: PPG CLI/PPG CLI/CommandPalettePanel.swift
• macOS settings: PPG CLI/PPG CLI/SettingsViewController.swift

Acceptance Criteria

• Sidebar shows full project/worktree/agent tree with status indicators
• Home dashboard with project cards, heatmap, commits
• Command palette spawns agents
• Settings persist and apply live
• Split-pane grid with keyboard shortcuts
• Prompts/Swarms/Schedules/AgentConfig views functional
• Session persistence and restore
• Multi-project support
