Move parent independant of children - transform mode

Just like the "Origin" transform mode proposed here:

Right-click Thread

I'd like to propose another transform mode:

• Parent Transform

or

• Child Transform Compensation Mode

Case

When you have a group of objects nested inside a parent, or even objects as children of bones - sometimes you want to only move the parent without moving the children.

Sometimes you need to reposition a bone but not it's children. Sometimes you need to move the house's door but not it's hinges. Sometimes you need to nudge the item but not it's accessories. Sometimes you need to move a machine part but not it's entire hierachy.

Current Blender workflow:

1. Select children
2. Unparent children
3. Select Parent
4. Move parent
5. Select children then parent
6. Reparent children

OR

1. Select children of bone
2. Unparent children of bone
3. Select bone
4. Move bone
5. Select children then parent
6. Parent childrento bone

Task

Create a transform mode that momentarily "disconnects" the parent/children relationship - freeing up the parent transform without affecting children.

Examples

Softimage has this.

New Workflow

1. Activate the Child transform Compensation Mode in Object or Edit mode
2. Select Parent
3. Move parent
4. Disactivate the mode
