Latest action colours

It would be really useful if you could choose the background colour for the Progress position ie 'Records requested' in red is fine, but 'To review' would be good if it was green - as I have done the work and passed on for review, I will not be able to do anymore until it has been reviewed. It would just make it clearer when scrolling through the task list. 'Records received' maybe yellow, 'In Progress' blue etc. I guess it would be easier if you could personalise these in settings as different people may use them differently, and they will have slightly different meanings within different businesses.
