Enhanced tools for positioning and sizing objects

From the discussion "Afix a button exactly on a specific area despite window resize"

"For a nice execution of what you are talking about, Softpress Freeway has a great solution. When Freeway 6 came out they introduced more options such as "flexible" versus "stretchy" (?) which made things a bit confusing, but I like having the ability to specify a set percentage plus minimum / maximum."
