First, no way to see what is the playlist before. You need to start it to see its content. But the worst is: if you replace the playlist with the best songs of an artist for example and do Save, it will erase the initial playlist with the current contents with no warning, and no way to undo this. On Save at the bottom, you can't change the name of the playlist ! There must be a Save As, so one can change the name and not overwrite the old playlist by default. I lost many nice playlists like that. The three dots to change the name are misplaced. This should be offered when using the Save button at the bottom.
