Component's Attributes - how to quickly change attributes

Hi,
I use the Component’s Attributes to change component’s size or position.
Unfortunately the basic way, so going into standard attributes window, isn’t a most convenient one.

Any idea how to improve this?
Best would be a plugin which eg. add a few windows with length/position values which I can easily change in the basic view of a project.

I’ve tried to find something like this - without success.
