The «Move» tool is nice.. but I very often find myself needing to either center something or rotate something around a specific axis (one of the three global axes or a shaft / etc).
Maybe something like that already exists but it seems at the moment that the best I can do is awkwardly drag the handles and hope that the parts don't move instead of the basis (and even then it seems to dislike doing things precisely which is ok for sketching but horrible for engineering 🙂
