Hoping someone can help me on this one - I had to restart my work computer and now I have a different layout which is very unfriendly and I cannot edit my playlists.  This layout is showing on Firefox, IE and Chrome.

The old layout had the playbar at the bottom of the screen, a search space in the upper left corner, with a text list of playlists below it and allowed the playlist or queue to fill the remainder of the screen.

The new layout is vertical stripes with a toolbar, playlist bar with album cover pictures, playlist and finally play bar stuffed into the upper right corner.  I have seen this layout appear previously, but then it would suddenly change back to the layout described above.  In this vertical stripe layout, I cannot re-order any songs in any playlist.  I have tried to sort by song, artist, album and even song length, but none of them are clickable. I cannot drag a song playing to a playlist, but have to click through the menu, add to, then finally the playlist name. In addition, the column of "date added" is completely gone and the "followers" notification is cut off at the top.   Song titles, artists and albums are all squished and do not display fully due to space limitations.  I am unable to expand the horizontal size of the column either.  I have dragged the window itself to fill 2 screens, and the columns remain the same size, with more black between them.

Is this the current layout, and if so, is there a way to change back?  Or at least a way to edit the playlist?  I was editing a playlist just before restarting, and now it is completely locked.  As it stands, this is completely unusable and ugly. 

For reference, this morning, I had a layout like this:  http://vab.com.au/wp-content/uploads/2016/01/try-these-25-great-apps-services-without-paying-a-cent....

Now, it looks like: https://41.media.tumblr.com/960cd2c1e889406b78ce8a6936211a2b/tumblr_n3krpsRKWk1syjm0ko1_500.png - only much less space in the center column
