When I eventually navigated to my Playlist 1, I wanted to delete a few videos but that took seriously too much time. The visibility of the Edit Playlist button (below) was poor - placed above a brown deleted video notification and the playlist header AND it was colored in black on a dark gray/black gradiated background (there should be more contrast!). After clicking the button to invoke the edit mode, I had to select checkboxes for each video and then locate a Remove option in an Actions dropdown. This was too many steps for a simple and frequent task.
