CODEX SHIPS RESPONSIVE TABLES AND FIXES TMUX INPUT HELL

By RepoJournal · Filed · About OpenAI

The TUI can now render Markdown tables that survive terminal resizes and streamed responses, while Shift+Enter finally works inside tmux.

Codex's TUI rendering just got serious [1]. Tables no longer collapse into unreadable wrapped text — they now reflow responsively while preserving the raw Markdown source needed to re-render after width changes, keeping transcripts legible through streaming, resizes, and scrollback. That's the kind of UX detail that separates a tool you use from one you tolerate.

In parallel, the team fixed a maddening tmux quirk [2] where Shift+Enter was arriving as plain Enter even with extended keys enabled. Codex now detects tmux sessions, reads the active extended-keys-format, and requests modifyOtherKeys mode 2 to keep the Shift modifier intact in csi-u panes. If you've been frustratingly submitting half-written prompts instead of newlines, this one's for you.

On the plugin side, installed Git-sourced marketplace plugins now populate metadata from the active cached bundle [3], preserving category precedence so list behavior matches read operations. Fallback logic stays intact when cache or manifest is missing.

Finally, the issue digest no longer counts the same user multiple times per issue [4]. Single-user comment and reaction spam can't artificially inflate an issue's importance anymore — the system now deduplicates by unique GitHub users while preserving raw counts for detail output.
