Here are some pics of NRG's cooked QMenu.
Again, this is Energy.RHODCDMA.21916.Sense2.5.Cookie.Sep.18
Fresh flash with no changes to seetings and default Page Pool of 22. Toggled to QMenu with NRG link in Settings folder and soft reset. - About 93MB free
Oh, and the menu is activated by pressing either the Windows icon on the top left or pressing the Windows button on the bottom of the phone.
EDIT - I had originally used the QMenu link in the tools menu. This did not disable the Start Menu. All it did was load QMenu.
Then I found the Compact Start Menu link in the Settings folder. It disabled the Start Menu and replaced it with QMenu.
