add an option in the option dialog : "selected items of inactive grid back color"
In an inactive grid (ie: a grid that doesn't have the focus) the fact that the item selection visual cue persists OR that the selected items back color doesn't change at all when focus moves from one grid to another (in a horizontal or vertical tiling of 2 or 3 different grids) gives the wrong impression : the inactive grid(s) seem active even if not.
I already suggested better visual cues to make the active grid more obvious -- and I know that there are some limitations due to the grid component.
However, if the "item selection visual cue" could change (different colour) when the grid is inactive, it would be much clearer -- and less easy to start typing at wrong place.
Could that be set in the options ? Something like "selected items of inactive grid back color" ?
