Codex App file manager: support drag-and-drop import and right-click delete

Feedback

Please improve file management in the Codex desktop app file tree. Two small actions would make the workspace file manager much more practical:

1. Allow users to drag files or folders into the Codex file tree / workspace so they can quickly add assets, documents, screenshots, or project files without switching to VS Code or a system file manager.
2. Add a Delete action to the file/folder right-click context menu in the Codex file tree.

Current behavior

In the Codex desktop app file tree, right-clicking a file currently shows options such as:

• Open in VS Code
• Open with
• Copy path
• Add to chat

There is no obvious way to delete a file from this menu. To delete files, users have to switch to VS Code, use the terminal, or ask Codex to run a command. Likewise, adding local files into the workspace is less direct than a normal file manager because drag-and-drop import is not available.

Desired behavior

• Drag a local file/folder into the Codex workspace file tree to copy or move it into the current directory.
• Right-click a file/folder and choose Delete.
• Show a confirmation prompt before deleting, especially for folders.
• Refresh the file tree automatically after the operation.
• Ideally support undo/move-to-trash where the OS provides it; otherwise make the confirmation clear.

Why this matters

Codex is increasingly useful as a primary coding/workspace surface. Basic file-management actions should be available without leaving the app. Drag-and-drop import and right-click delete would reduce context switching and make common workflows, such as adding images/assets and cleaning generated files, much smoother.
