The Method Grid store is where you can find pre-developed grids ready to be downloaded to your my grids folder for customization.

As at current release, the store only holds free-to-download grids. In the future, we envisage this store hosting grids for sale (single payment) thus allowing for grid developers to trade their intellectual property. 

You can effectively download (or "clone") grids from the store to your my grids folder. Once in your account's grid library, you can edit the grid and all its contents as per normal. To give access to your wider team, just move the grid from your my grids folder into your grid library folders.
