Grid visual aids

In Dw CS6 there is the visual aid of Grid, (under, View -> Grid) -

Whilst experimenting with the creation of a css grid layout, I found that the old, (removed from CC) grid visualization tool would have helped in working out the grid layout. In CS6 this is only available in design view, and would have to be available in live view to be of real use.

I would like to propose that this feature is brought back into Dreamweaver as soon as possible, in order to assist users when developing sites using the css grid layout module, the css flexbox layout  module and the css multi-column layout module.
