Grid functionality

On the grid. Can you make the sizing dots available on all sides so don’t have to scroll to edit sizing. I know you guys looked it already, but if there’s a way to make adjustments based on the lines rather than the dots, it would be helpful! I’d also like to be able to set breakpoints on the grid boundaries with variables. This would really allow me to replace too many layers with grid and build tables with grids. Cant really do this now.
