Math and equations render properly, drag-and-drop file upload works in the chat window, full-screen mode is available, loading messages are clearer, and citation tooltips show sources on hover.

Equations display correctly — no more raw LaTeX in your chat.

Drop files directly into the chat window instead of hunting for an upload button.

Expand to full-screen when you need more room to read long answers or work through a thread.

Loading messages tell you what the AI is doing, and hover a citation to see where an answer came from.
