One cable-hiding idea, that might not 'float' in the consumer market*, is a set of 'pigtails', leaving the connectors-on-cables you don't need retracted. That way only the power cord needs a right angle end connector. And, unless your kids are into furniture tipping, switches and knobs underneath keep the settings generally out of the way of little fingers.

* Consumers are taught what to expect and generally don't want to deviate even if the deviation is toward improvement. Then, again, we are Outlaws! If we hadn't deviated from the mainstream at least a little bit, we wouldn't be here :-D
