Update after using the new ChatGPT.app for a bit: Lots of old ChatGPT functionality missing:

  - No voice mode
  - No Deep Research
  - No explicit Search toggle 
  - No Record mode (meeting summarizer) 
  - No Canvas (good riddance) 
  - No custom GPTs 
  - Old chat threads are hidden (have to open a new chat, then click “See all” under “Recent chats” – or use the “Search Tasks…” function)

Does the new ChatGPT app still separate ChatGPT and Codex usage quotas, or does all usage now count against the Codex limit?
