The things about object size

If I trying to change object size,it is a little bit troublement because since using transform tools,each coordinate values must be set each time.Some objects broke temporary.

So,I suggest the tools that change size more easily and keep the things.

For example,since finish the modelings,enter the X coordinate values(In this case,length). Then Y coordinate values(In this case,height) and Z cordinate(In this case,thickness)are setting automaticly!

So I hope to add this tools to modeling easily. Dear love.
