Title:
Codex desktop app regression: missing Chinese localization (Simplified/Traditional) and missing context usage indicator

Description:
The current Codex desktop app has two UI regressions.

1. Chinese localization is incomplete or unavailable.

Both Simplified Chinese and Traditional Chinese do not display correctly in the Codex desktop UI.

I tried:

• Setting macOS/app language to Simplified Chinese
• Setting macOS/app language to Traditional Chinese
• Setting com.openai.codex AppleLanguages to zh-CN
• Relaunching the app
• Testing older Codex versions

Major UI labels still remain in English, including:

• Personal account
• Usage remaining
• Log out
• Settings
• Ask for approval
• What should we work on?
• Do anything
• Work in a project

Expected:
The Codex desktop UI should support Chinese localization for both Simplified Chinese and Traditional Chinese, or provide an explicit app language setting.

Actual:
The UI remains mostly English.

1. Context usage indicator is missing or no longer visible.

Older UI appeared to show context/window usage near the composer/model area. In the current UI, the area next to model selection is blank, and only model + reasoning effort such as “5.5 Medium” is visible.

Expected:
A visible context usage indicator, preferably percentage/token usage, should be shown in the composer area.

Actual:
No visible context occupancy indicator is shown.

Why this matters:
Context usage is important because high context occupancy can reduce response reliability and increase hallucination risk. Users need visibility into context usage to decide when to start a new chat or reduce context.

Environment:

• Codex macOS app
• Version observed: 26.602.71036
• Also tested older versions, but the issue persisted

What steps can reproduce the bug?

1. Open Codex desktop app on macOS.

1. Set macOS/app language to Simplified Chinese or Traditional Chinese.

1. Relaunch Codex completely.

1. Open the main Codex window and the account/settings menu from the lower-left sidebar.

1. Observe that major UI labels still appear in English, such as:

• Personal account
• Usage remaining
• Log out
• Settings
• Ask for approval
• What should we work on?
• Do anything
• Work in a project

1. Look at the composer/model selection area.

1. Observe that there is no visible context usage indicator, only model/reasoning effort such as “5.5 Medium”.

What is the expected behavior?

The Codex desktop app should fully support Chinese localization for both Simplified Chinese and Traditional Chinese.

When the macOS/app language is set to Simplified Chinese, the Codex UI should display Simplified Chinese.

When the macOS/app language is set to Traditional Chinese, the Codex UI should display Traditional Chinese.

If automatic language detection is not supported, Codex should provide an explicit language setting in the app settings.

The composer area should also show a visible context usage indicator, such as token usage or percentage of context window used, so users can understand when the conversation is approaching context limits.

Additional information

This affects usability for Chinese-speaking users because many key UI labels remain in English even after changing system/app language settings.

The missing context usage indicator is also important because users need to know when context usage is high. High context usage can reduce response reliability, so users need this information to decide when to start a new chat or reduce the amount of context.

Tested version:

• Codex macOS app 26.602.71036

Also tried:

• Setting macOS/app language to Simplified Chinese
• Setting macOS/app language to Traditional Chinese
• Setting com.openai.codex AppleLanguages to zh-CN
• Relaunching the app
• Testing older Codex versions

The issue still persisted.
