艦これPIP

Overview

This is a Chrome extension that allows you to display the Kantai Collection game screen in Picture-in-Picture (PiP) mode. Since it's merely rendering, you cannot operate the game through the small screen. Once installed, there will be a faint PiP icon in the upper right of the game screen—click on it to use it.

※Currently under review for the Chrome Web Store. Even if it doesn't get approved, you can use it normally by following the instructions in the README within the GitHub repository.

Additional Note

It looks like it probably went through.
