I don't know why people are complaining about Gantry 5. Im never going to use Gantry 4 again!!!
Really easy to add grids, blocks and spacers into Joomla articles in code editor mode. Rokpad is essential for this as my favourite editor just mucks the code up on saving. Also adding extra sections is really easy once you get the hang of it and place them in the right directory in the template Custom folder.
