When a user clicks the "Manage Grids" menu option, and the Manage Grids dialog box appears, I think it would be good if the current grid were highlighted immediately in the list of grids.  This would eliminate the step of locating and clicking on the current grid in the list of grids.  Right now it's just highlighting the top-listed grid in the Manage Grids dialog.

 

Right now I see several ways of getting to the properties for the current grid:

 

(1) Grid menu > Properties

(2) Tools menu > Manage Grids

(3) right click tab for current grid > Manage Grids

 

I think it would particularly make sense to highlight the current grid when the path selected is (1) or (3).
