Proposition of new tools for unity components

A lot of tools can be made to improve native unity components. (tools directly accessible from the components).

Are you interested about a components extension library ? Why ? Does it feel like "too much" to have extension directly plug in native components ?

(sorry for the poor video quality)

I have some idea:
- like in the video: move parent and keep children in place
- copy / past button for Transform (a classic one, but still relevent, exemple: http://www.belfiore.ovh/devlogs/components-extension/components-extension.php)
- Auto fit button on colliders: to automaticly fit colliders to mesh
- Move pivot of a meshRenderer
- Change center of mass of rigidBody (exemple: http://www.belfiore.ovh/devlogs/rigidbody/rigidbody.php)
- automaticly play animation of an animator (exemple: http://www.belfiore.ovh/devlogs/animator-extension/animator-extension.php)

And many many more.

Please give me some feedback about your thought about it. Thanks!
