Feature
The text is in charge: whatever you disable in the text disappears from the video. Select a section in General transcript (click and Shift+click) and Create sequence turns it into a sequence; in the editor, Delete disables the selected words.
Always: it's how you edit in Max, with or without AI.
It doesn't delete for good: Undo (Ctrl/Cmd+Z) and Redo go back and forth, and disabled words stay in view.
The transcript. It doesn't need AI.
