Stretch gives you the ability to create selections that stay 'in sync' across multiple rows with different quantities of fixtures. Selection grids can be stretched so that fixtures on multiple rows stretch to fit the X/Y/Z length of the selection. Meaning speeding up the process to align fixtures so phasers run in perfect symmetry. You can also specify your own grid width, instead of letting the plugin calculate the stretch amount needed, to give your fixtures more space if needed, or to compress the grid to your required width. In this way the tool can be used to simply resize your grid in all three directions - X, Y and Z.
