Coloured power bars for schedules

Got an idea. On schedules why not have a colour power bar that slowly go’s left to right say starting on green then moving to amber to red the close it due to be paid. So at a glance you can see all the payments due by looking at the colour of the power bars.

If it was very very thin yes.

If not then I’m wary this would clutter the UI quite a bit.

Like the principle of this though, but it’d have to be very well designed or could be an eyesore?
