It would be nice to have the ability to keep several playlists or search results open in a similar fashion that Web Browsers use tabs to have many different pages open and easily accesible.

Your idea was submitted a while ago and unfortunately didn't receive the amount of kudos needed to stay active in the ideas board (100 Kudos per year).
In order to keep the Ideas Exchange clearer I'll close this idea for now, but this doesn't mean Spotify rejected this idea.
If you think this is an idea which needs to be implemented, you're welcome to post it in a slightly different form 🙂
Have a nice day!
