If objects are not within a group, they should have the ability to apply transformations (e.g. scale, rotate, etc.) to the objects separately and not as a total selection state.
This also relates to object-specific calibration (e.g. centre; top-left, middle-right; etc.).
Nice suggestion. There is a free macro for multi objectresize; CT_Multi_Resize_3.5
You can use it until Corel DEV bring that feature on CorelDRAW ;)
