The rotate feature in QGIS 3 allows you to select multiple features at once and rotate them around the centroid of their combined geometries, as found in the documentation.
You can also use an anchor point different from the default feature centroid by pressing Ctrl or if you hold Shift before clicking on the map, the rotation will be done in 45 degree steps, which can be modified afterwards in the user input widget.
I would like to rotate a selection of multiple features around each features individual centroid? Is this possible?
