While it is highly unlikely that the basic movement is gonna get changed at this point, I think that there is a possible tweak/solution to the "jump as a bonus action" debacle that's bothering quite a few people out there - that would be the introduction of a running jump, something that the rules cover.
What if jumping were to cost no action, but jumping anywhere decently far would require first expending part of a character's movement-per-turn to do it? That would cut down on the amount of bunny-hopping and make it a tactical tool mostly meant for getting across hazards and elevation, but at the cost of mobility during the turn the jump is being made on. Standing jump should then either not go further than being a way of getting out of being body-blocked (drawing all the opportunity attacks as it's being attempted) and also either stripped of its BA cost altogether or the BA cost being exclusive to the standing jump, as you do not sacrifice your movement for it.
Someone probably made a similar suggestion already, in which case this should probably be merged, but it still is a somewhat bothersome aspect to how the mobility is handled during combat.
