Why can't searching for videos on a channel be like it used to be? Whenever you visited a channel's main page the search bar was automatically populated with the channel ID to search for specific videos from that channel:

The "fix" mentioned above is too much of a pain to go through. People just want to go to a channel and be able to search their videos from the get-go, nobody wants to painstakingly copy the channel ID evey single time they want to search for a specific video from that channel.

My comment was meant as a response to the closing of #2344, since it was wrongfully closed by this "fix".
