Sorry, maybe I looked over your question too quickly too.
In fordson on the main settings page you can choose one of two options for displaying blocks: Boost Default or Fordson 3 column.
If you choose Boost default the Add a block button appears in the navdrawer and there is only the side column on the right to put the blocks.
But, the Add a block will not put blocks in the nav drawer. That is just replicating how Boost works to add blocks.
Fordson has a sliding "Block Panel" which is 3 columns and is hidden in the top of the screen.
This is a video of the very first implementation of blocks in Fordson with the sliding drawer.
