Description

This PR adds a small improvement to the prompt comparison functionality.

When the two prompts are different, the tooltip overview now enables clicking on modified parts to navigate directly to the corresponding lines.

Previously, finding the modified parts required manual scrolling. With this update, it becomes much easier to locate and review the changes, even for very long prompts.

When navigating to a modified part, the target line is highlighted in yellow for 1 second to indicate the clicked location.

For mobile devices, this functionality has been tested on iOS 16.7.

If there are any suggestions for improvement or concerns about the implementation, feedback is greatly appreciated. It’s completely understandable if this PR needs to be rejected or revised further.

Thank you for taking the time to review this!
