Indicating active box in transform panel

[MickRose]

I've only just noticed that if I use the tab key to go to a particular box in the transform panel, then there is a tiny blue box round it. It looks like 1 pixel thickness. Its so hard to see I have always thought there was nothing at all to indicate the active box. The same applies to various other boxes - for instance document size and the bleed size. I would like to see either a much thicker line or have the active box the same as if it had been mouse clicked.
