so we could understand which value is X Y or Z
that's why the arrows have colors
but they dont define anything
every modeling software has its difference
in colors and orientation
when you move a node it will display the direction
in 3D's max for example Z it height
in Maya Y is height
yes great that we already know
the people who had background in 3d graphics
who doesnt know what is XYZ and what colors define which direction
but when you move something it tells you
oh ye right i forgot about that
okay but it shows the direction only when i drag the object
since editor doesnt have ctrl+z function it makes it complicated a bit
Tbh the editor is limited in what it can do, there's no need for undo
