User for >4 years. Absolutely love the nifty little tool. But I hated opening up a terminal each time I wanted to initiate a download.
For PopClip[1] users on Mac, I made a little YouTube-dl extension[2] which lets you initiate the download just by selecting the video URL (best when done from browser's address bar) and clicking a button. Been using it as my primary ytdl client for past 5 months now.
