Currently players are teleported to their spawn point if there is no valid space within the knockback limit.

I would like players in creative mode to just be knocked back horizontally.

Well, I'd like to be able to turn it off per world or per player (i.e. permissions), but that would just be a bonus.

Should be addressed by this:

Hmm, fair enough; if a player is flying or possibly just in Creative mode, a solid block to stand on shouldn't be necessary. I'll add that to my "to-do" list.

Cool
