Differential pair routing
Pin swapping... ie a differential pair where the pins can be reversed
Pin agnostic routing, ie a MCU or FPGA where it doesn't matter which pin is used
Incremental part placement, unlike kicad where all the footprints get dumped on the board in a big mess at the start
These are things that bother me most in kicad (it does have diff pair routing)
Thanks - looking forward to taking it for a spin
