it would be much easier to maintain grids if  "grid groups"  and "Description" from the "Properties of grid" (right side) could also show as a column under "List of grids" (left side).

And even nicer would be the ability to toggle on/off the columns in "List of grids" (for example I don't use the Alt+ column).

Nicest of all would be dropdowns on the "List of grids" columns to pick any of the options from the "Properties of grid".
