Now I see them. Yes, adding labels would help to get the '+' and '-'
symbols more visibility.

There is a very old ThingLab video which is the best demo I've seen:

http://www.cs.washington.edu/research/constraints/videos/thinglab-1978.mov
http://www.fit.vutbr.cz/study/courses/OMP/public/software/sqcdrom2/Documents/ThingLab/ThingLab-Chapter_5.html

With Constraints you will have a way to say:
-When a user resizes a window, then mantain the font proportion to
stay into the boxes.
-When a window is updated with a new figure (a sibling in the UML for
example) then update the remaining siblings to preserve symmetry, etc.

Summarising, with constraints you say what do you want to achieve, and
not how to do it. The layout adjustement algorithm will use
constraints to achieve it. There is an implementation of constraints
solvers in Squeak called Cassowary
