[Windows][Desktop] Attachment removal and message actions are hidden until hover

What version of the Codex App are you using (From “About Codex” dialog)?

26.908.9136.0

What subscription do you have?

ChatGPT subscription (exact tier is not shown in the Codex App)

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

In the Windows Codex desktop UI, important controls are visually hidden until hover or keyboard focus:

• The remove control for an image pasted into the unsent composer.
• Message controls such as Copy, rating, and timestamp.

This makes accidental image pastes difficult to undo and basic actions undiscoverable. For attachments, this is a send-safety issue: a user can accidentally send the wrong image before discovering the hidden hover target. No error message is shown.

What steps can reproduce the bug?

1. Open any local Codex task in the Windows desktop app.
2. Paste an image into the message composer.
3. Move the pointer away from the attachment thumbnail.
4. Observe that no remove control is visible.
5. Hover the thumbnail or focus it with the keyboard; the remove control appears.
6. View an existing message without hovering; Copy, rating, and timestamp controls are also hidden. Hover the message and they appear.

This reproduces consistently in dark theme and is independent of a specific task/session.

What is the expected behavior?

The remove button for every unsent attachment should remain visible at all times. Please also add an accessibility/display setting such as “Always show message actions”. Hover may reveal secondary controls, but a control that prevents accidentally sending the wrong attachment should not depend on hover.

Additional information

No private screenshots, chat content, task names, or local paths are attached. I searched existing openai/codex issues for an exact duplicate using attachment/remove/hover terms and did not find one.

No source file, test, or entry point is named in the report. Reproduce the issue in the Windows desktop composer and an existing message, then trace the attachment and message-action UI; done means the unsent attachment removal control is persistently discoverable and the requested message-action visibility behavior is covered.
