Split view has finally been added back as a new experimental option. It was marked as experimental since its definitely not 100% perfect right now and it could take some time to get right. I'll continue to make improvement over the beta but it will most likely stay experimental until sometime after 3.0. What exactly does experimental mean? It simply means that things may not work correctly and users should not expect them to be fixed any time soon. The option can be found under advanced settings -> UI. Split mode has a different set of default settings compared to regular view, but most things can still be customized like the album art background and all that.
Beta 10 also added the ability to customize the displayed metadata in most of the views (folder view and a few others will be added in Beta 11). This works basically the same way as now playing does except the available variables are different depending on the view. I'll be updating the documentation on the forums to list which variables are available to each view. If you try to import a custom metadata line that has an unsupported variable, the import will fail and you will get an error message.
Just like now playing, there are a bunch of presets to choose from, however some views that only expose a single variable (like artist, albumartist, genre, and composer) do not have many variations at this time. My hope is to expose some new variables to those view like "total albums", "total artist", etc to allow a bit more variation.
