Page Management in 1.28

All,

I noticed in the Summary thread for what's new in 1.28 there is a note about page management.  I personally do not see this option in Compose.

I can add.  That's it.   There is a small up arrow on bottom right corner, but nothing expands up.  There is no page sorter.   My install?  or is this something that isn't working quite right?

thanks

james
