Splitting off some bad advice

Dunno quite what you mean by this. There’s one 3.3 v pin, two adjacent 5 V pins and a sprinkling of ground pins around the connector. Can’t be too difficult.
Regard the ground pins as a friendly gesture to make your own layout easier.
And don’t fall into the “aesthetic” trap of making all tracks as thin as the PCB maker accepts (like 15 mil). Bad engineering.
