IO-Boxes:
- Vertical scaling happens from the center.
- Horizontally they scale from the left.
- Scaling is only possible to the right / bottom.
- When hovering the border / part that allows scaling the cursor changes accordingly (same goes for nodes).
Regions:
- Scaling is allowed from/to all sides.
- They scale from the opposite side/corner not from the center.
- The cursor does not change.
Especially the first and the last point are kind of annoying.
