Ok, so my circuit will work, but can be improved. I get it.
One side of me want to make an 100% bulletproof breadboard power supply, but on the other side i wil never use two power inputs at the same time.
I want to make it sofisticated with chips an more advanced circuit, but my knowledge is'nt there yet.
I have tried to look at the breadboard supply we can buy from Aliexpress, adafruit etc. and i can't find them specially sofisticated either. They have two power inputs, one diode, two regulators and maybe an power led with resistor and a couple of capacitors.
I just want to make an more sofisticated version of that, but i know my knowledge isn't there.
