It's the only plugin that I found which displays a fluid grid and thus consents to replicate a bootstrap 4 grid.

It misses an useful feature though: the grid is not persistent after you refresh the page, you have to always recreate the grid, which is obviously a pain in the ass...

Some suggestions:
- add a toggle to show/hide the grid without deleting it after a page refresh
- add the possibility to invert the colors of the columns and the gutters (columns are transparent, gutters are colored)
- add the possibility to add different grids for different breakpoints
- add the possibility to save (with a name) different grids settings
