Hello

at first it's good to know that someone appreciate changes.

in this case island to polygon. And it's only action provided directly by
QGIS which creates multi part geometry. Tool Remove Part was introduces
because it works not only with polygons but is able to delete also part of
multi-point or multi-line feature. As I know QGIS isn't able to create them,
but they can be already in some shapefiles, so it's good to be able to
delete part of it. That's just reason why it's called remove part and it's
not deactivated on point or line geometries.
