Filter your youtube subscriptions page by hiding videos that matches regexp string in the videoMatchHide object;
Keys are channel names you want to filter, values are arrays of regular expression strings. For example if you want to hide all videos starting with "test video" from "test channel" you need object like this:

videoMatchHide = {
"test channel": ["^test video"]
};

If you want to match all videos from all channels just use key "*":

videoMatchHide = {
"test channel": ["^test video"],
"*": ["^test video 2"]
};
