The "Heart Button Mover" is a Chrome add-on developed by HinaiNanaha, available for free. This tool allows users to move and adjust the transparency of the heart buttons in the YouTube chat section. It shifts the heart icons from the bottom right corner of the chat to prevent overlapping with the lower messages, ensuring readability. Moreover, it offers the option to make the heart buttons transparent to maintain visibility even when they overlap.

Compatible with YouTube's live viewing page and YouTube Studio's live management page, this add-on aims to enhance the user experience by optimizing the placement of heart buttons during live streams.
