Use the Dash Macro for more precise movements.
Most fighting games allow a dash via double-tap in the direction of your choice. MBTL incorporates a Dash Macro, which means you only have to press one macro (A+B) to dash. One trick for mixing recovering opponents is to jump-dash-meaty them. Pressing jump-A+B-attack is much easier than pressing up-forward-forward-attack. It's even better when A+B is assigned to a shoulder button.
