The NicoNico Like List Tool is designed to list users who have liked your videos on NicoNico Douga. It allows you to gather and copy the list of users who have liked your videos, offering the option to sort them by date instead of prioritizing premium members. Once installed, a new button "Copy Likers" appears next to the "Users who liked" section in your video analytics on NicoNico Douga. By clicking this button, the tool retrieves and writes the list of users who liked your videos to your clipboard. Additionally, you can choose to sort the list purely by date, disregarding premium membership status.

Please note that due to limitations where only 20 users who liked your video can be retrieved at a time, the tool communicates with NicoNico's servers multiple times. It is advised to use it judiciously to avoid overloading the server. Also, the more users who have liked your video, the longer it may take to retrieve the list. Patience is recommended during the retrieval process.
