In the JellyFlix theme, in default.css line 1907, it includes this code:
#itemDetailPage .vertical-list {
display: grid;
This makes playlists display in a grid, filling up a horizontal line before going to the next row. This makes reading and arranging playlist orders pretty much impossible. I would like to request that "display: grid" be deleted so that the playlists can be arranged one item per line. This would allow dragging and dropping playlist items using the included listViewDragHandle.,
