I think it's not compatible at all anymore with ZP 1.4.5. After the upgrade to 1.4.5., Masonry did show a multiple amount of errors so I decided to do a totally clean install of ZP 1.4.5.. After that, Masonry did not work at all anymore: just a totally empty grey view with an error about the Admin Toolbox was shown.
As announce by its creator and also that he is working on updates:
