Cubik Studio

Edit mode: Element
Location: Edit
Function name: Set all elements position as its origin
Function icon: The red, green, and red xyz arrows

Function action details:
Will set all the selected elements' position as their origin for MCPE models

If this is what I think it is, it could solve a lot of my problems with the current version.

The Reset button (anchor icon) does that already. It moves the origin back to the element(s) position
