Right and the icon is for a final state ;-)

I would also like to contribute here. About state machine a good start 
would be
to define shapes for superstate, parallel decomposition, start and final 
states,
reuse the existing state (for backward compatibility), transitions (with
a property textfields for event [guard] / action

There is also probably some work to do to get more complete support in
- class diagrams (eg. nary relationships, associations classes)
- activity diagrams (eg. subsystem, vertical fork/joins)
etc (check against a good UML reference card or even the OMG spec)

Another point which was discussed previously is about structuring sheets 
into some packages.
With more UML shape, the sheet could become a bit overcrowded and  it 
may become useful
to split the sheet into several ones, redesign the interface to manage 
categories, a set of working sheets,
etc... I wish I could prototype sth... As soon as I get some free time 
to have a try.
