Oh my fuck, I was led to believe that the Codex Mac app was native. Codex itself said so. Google also said so but now it says different.

Codex definitely "feels" more native than Claude: Proper menus etc, like when you right-click on a session in the sidebar, Codex shows an actual context menu, whereas Claude reveals its HTML-rendered jank and highlights the word you right-clicked on as if the sidebar item is just a plain textbox, ugh
