YOUTUBE PLEASE DON'T REMOVE THE OLD LAYOUT FOR EDITING PLAYLISTS

Please don't remove the old playlist feature to edit it. I use it daily for all of my playlists to move songs very easily through the playlist. I'm using the End, Home, Page Down & Up keys and click on ''Load more''. Every click is 100 songs loaded.
The new version also does have this, but I only can see 7 video's instead of 10 video's on 1 page which makes it more manageable and it also gives a detailed look on the playlist.
Also the numbers of the songs aren't displayed anymore in the new layout. (only if you play the video). And you can also click accidentally on the ''recycle bin'' button if you play the video in the playlist. If you change a video into the new layout it reloads the playlist at the 100th song.
Which I can easily lose where I am into the playlist and that actually looks then like a bug. The old layout doesn't reload the playlist if you change a video into it.

Every new video that I add to the playlist will be added at the bottom of the playlist which is the last number. So I have to go through the full playlist for it in order to change it to a different number into the playlist.

The ''bug'' that I was talking about @5:50 wasn't a bug, but it was a function into Firefox that was enabled. I had to press on the ''F7'' key to disable the function.
