Hit enter to download

Thank you for your excellent application. I love it and I have two items of feedback: 1) After you've pasted a link and selected your quality, I would love it if you could just hit enter to download. This would save moving the cursor all the way over to the 'Download' button. Currently, if you hit Enter, it just cancels the download, which caught me off-guard at first because I thought I was downloading videos by pressing Enter. 2) I also have another suggestion. Sometimes I want to download something so I can extract the audio from it. One might think that downloading the highest resolution would provide the highest quality audio, but that is often not the case. Therefore, it would be great if your application could display the audio bitrates as well as the video resolutions. Thank you again for your excellent application. Long live 4K Video Downloader! :)
