Ability to place ramps without getting off

So during some of the missions theres parts where you dont seem to jump high enough or pretty hard and trying to place a ramp makes you get off your board which then makes you respawn/restart for getting off it. So making it so you can put stuff down without getting of your board or respawning would be nice.

Also a better or more consistant jump height would be nice (already using 100% pop height too)

And last thing is you fall of your board way too easily.
