Found this launcher last week and I've been playing with it since.
It still works with "muscle memory" but instead of placement, it's the gesture (or direction) that triggers the action. With time it can become quicker and easier, i think, than lawnchair, eblan &c or search based launchers
I have use Pie launcher before which has a similar idea.
In the end I settled on KISS, setting apps to launch with swipes in the four cardinal directions in addition to the whole KISS common/search/favourites setup.
