• Added multiple replacements: run several different find-and-replace pairs together.
• Added per-replacement match counts and results.
• All replacements use the original page text, preventing unintended cascading changes.
• Overlapping matches are handled predictably, with the earlier replacement taking priority.
• One Undo action now reverses an entire multiple-replacement operation.
• Improved sidebar responsiveness and prevented inaccessible iframe warnings from hiding controls.
