Now that we have primary type and secondary type and Compilation and Live have been demoted to secondary types there is no way to group live or compilation albums. Although we can see the secondary types at the end of each title that is no help in trying to group releases.
We need a better solution, perhaps filter buttons could be added to just show a particular secondarytype. Or I previously suggested another column containing secondary types so that when sorting is added you could sort by secondary type. Now the objection was that this wouldn't work very well because you can have many secondary types, which is true, but in the real world I think most of the time there will only be or two secondary types so it will work well enough, certainly better than the current display. Another objection was the space it could take, but we could use icons instead of words.
