Could I suggest the following defaults for grids (see screenshot), which is a bit sleeker and moves away from the ‘ecco’ colours which makes our cutting edge tool look a bit 1990’s if you aren’t an ecco refugee!  This also resolves the issue where default colours make gantt bars nearly invisible when selected.  

a.       Selected Items Back Colour: &H00D8D8D8&

b.      Grid Items back colour: odd &H00F0F0F0&

c.       Grid Items back colour: even &H00FFFFFF&

d.      Ecco style bullets: off (non ecco users will not know these are effectively tree nodes)
