Description _ tboudreau 2006-09-06 07:14:20 UTC

The biggest problem I have with the UML designer at present is the fact that, to
fit enough information on screen to do something useful, everything is too small
to read.  Scrolling around requires constant mouse gestures - it makes for a
serious usability problem.

Something that would make it much more usable would be non-linear magnification
- basically, a magnification area that tracks the mouse.

A good starting point for researching this:

For diagrams,we now have a navigator.  The navigator for a diagram now shows an
overview window.  In the navigator window, you can move around the diagram as
well as zoom the diagram.

Will this solve this use case?

Comment 3 _ tboudreau 2006-10-05 00:38:11 UTC

Neat use of navigator - it definitely looks useful.  At the same time, it's not
the same thing as non-linear magnification (i.e. one view serves as both the
overview and the detail view).  

So if you don't mind I'd prefer we leave this enhancement open;  at some point
perhaps we can try mocking up real non-linear magnification and determine if it
would solve the problem.
