It really is the trend at the moment but I would love to be able to change the colour scheme, particularly the open orders screen as it can be really tiring after a few hours of staring at the white background. Just something softer on the eyes.
This is something we thought of in the new Open Order beta. We haven't done much with it other than having designed it with provision to change colour scheme. Can't promise anything in form of ETA but certainly if we receive enough requests for particular colour schemes, we can do it with sensible effort.
Oh great to hear!
Hopefully other people want this feature.
Chrome should be able to do this itself by now :(
