TL;DR
Give audible feedback that the entity rotation action has been performed.What ?
When the entity rotation key is pressed, play a sound to serve as feedback that the action has been performed.Why ?
Audible feedback is important in games, so due to the proximity of the default E (properties) and R (rotate) keys on an English keyboard layout, it is very easy to accidentally press the R key instead of, or at the same time as the E key. Any entity under the pointer will then be rotated - usually unseen by the player - only to be discovered later when things stop working. Some entities, such as pipe to ground and some buildings, are difficult to spot that they are no longer connected.Audible feedback on rotation should serve to alert the player that they have performed the rotate action.
This is a quality of life request.
