Refine Send/New Line Behavior

I was so happy when T3.chat finally introduced the feature “Invert Send/New Line Behavior”

Now I send even more messages accidentally because I press Shift Enter by habit. Can’t you make a regular keymap setting like other apps (OpenCode for example)? Or just disable sending with Shift Enter—who does that anyway? Meta and Ctrl make sense. But Shift? That's just confusing.
