Ok so like when you're editing your playlist you get that menu where like you can remove songs and also move songs around I was just thinking like if you pressed the shuffle button while you're in that menu it'd like shuffle all the songs in the playlist idk it's kinda lame but I'd love that

On the mobile app, you can shuffle an entire playlist by clicking on the large green "SHUFFLE PLAY" button at the top of one of your playlists.
For more information about Shuffle Play, check out this Spotify support article.
Have a great day :)
