1: Jump definitely needs a hotkey. It gets used so frequently in exploration and it gets frustrating when I have to slow down to a crawl jumping one character at a time with sluggish control.
2: Jump either needs to be made into a full action in combat (and turn into a bonus action for Rogues), or it needs to be disassociated with Disengage. Ironically, this doesn't really depower rogues, but it does depower things like Shocking Grasp, making it total trash.
3: My suggestion is make Jump neither action nor bonus action, just movement. Add a new Disengage action. Add a new Rogue (and goblin, etc) ability called Disengage, which is a bonus action.
