TL;DR
QoL: When placing over a ghost (inserter/belt as an example) auto-rotate the placed item to match the ghost rotation.What ?
Simple QoL feature, if you place an entity over a ghost, for example, an inserter, it would change its rotation to match the ghost's rotation.Saving the player from the hustle of frequently switching rotation in complex builds and mistakenly placing it in the wrong rotation.
Why ?
Often I find it annoying when building repetitive patterns, especially in the early game and sometimes even in the mid-late game.One of the most common early builds is this: You have to place inserters on one side then rotate it and place it on the other, this inconvenience is almost forcing you to build this horizontally instead of vertically causing you to backtrack.
The issue is much more noticeable when building more complex things like this: Inserter and belts are placed in different rotation, constantly forcing you to change rotation.
In addition, this is very error-prone, especially with belts which are harder to notice visually.
