Some of those, like multi track drawing/dragging, are crazy useful.
As a side note, KiCad is currently running its 2025 fundraiser if you want to consider supporting them.
That's a dangerous feature set for Altium and friends. Multi channel is one of the last major features that Kicad was lacking. Hell of a turnaround from the project of 10 years ago.
