I dont seem to be able to sort by item (background) colour - is this possible?

 

I'm using colour as a sort of very simple tagging system - or more as a guide really.

In different grids colours have different meanings

e.g.

 

I suspect the only way is to set up fields for each of these colours (I've done this in another grid but they are grid specific and have other auto-assign rules too) or anyone else got ideas?

 -

If I made yes/no fields that change the colour & could then be used in various grids -

it would then be helpful if I could have a relevant name for field in each grid - or I could do as currently and have first few items explain the meaning of each colour (as in example above)

 

I tagged this feature request in case & can add it to mantis if apt
