and I'm the only one who doesn't like Canyon editor
too "slow" for me (lagging rotating/etc), and blocks panels popping up all the time when you don't want it are annoying imho... also you can't remove blocks by dragging over them, you have to click each of them. copy/paste is cool, but doesn't work (perfectly) with ground-to-air or vice versa.
blocks aren't my favorite too, but there's enough of them to make a decent and fun track. as it was already said, they're too big and have too many unnecessary sh*t around them to be really creative.
tho canyon handling is second favorite for me after stadium.
