be recognizable a shorten address

1. So far, 4k downloader for Youtube cannot recognize a shorten address. I can copy only shorten address from right-click context menu such as "https://youtu.be/abcdefg" intead of "https://www.youtube.com/watch?v=abcdefg". It is very big problem to open my wallet.
2. Please make a menu like 'force to download the highest resolution and fps'. If Youtube downloader extracts the highest option at once, the function will not be necessary. But it cannot so I usually cancel the process and retry many times until the highest option appears. This is enable when I try to download only few videos one by one, but I can't use this method when I use the 'smart-mode'. It try to extract few times and gives up despite it failed to extract the selected option.
Thank you
