Internally, we call this the \'Tiled Clones dialog on steroids\'. This new LPE allows for interactive tiling, using a huge range of different tiling types, setting the distance between objects numerically, changing scale, location, rotation per row / column or adding more rows and columns on the fly. This can be used to quickly copy large numbers of objects non-destructively and to create interesting grids and patterns and variations quickly (MR #3814).
