+// @name           WebNowPlaying Companion Listener
+// @version        1.1
+// @author         aminomancer
+// @homepage       https://github.com/aminomancer/uc.css.js
+// @description    Listen for updates from the WebNowPlaying Companion Addon, and set background timeout prefs based on whether a video is currently playing or not. If a video is playing, the min timeout values are minimized so that status updates will be sent from the addon to rainmeter as quickly as possible. This way there isn't a lag in the rainmeter skin's pause status after pausing a video. If a video is not playing, min timeout values are increased to conserve computational resources and reduce power consumption.
