Quite a straightforward one: there are panels on the bikes that can be cycled through a few options with the colour sliders, could we have a similar setup for jerseys/helmets as well?
It would only take a couple of generic designs with a changeable colour panel on them – e.g. black and your-choice; or black, white and your-choice – to really brighten up the field a bit (and let us pick gear closer to that we wear in real life) without needing to offer a full-on jersey editor and risk potentially offensive designs.
