You can use 'Interaction Use' tool from Sequence Diagram group in toolbox to add a Reference fragment.

Break fragment is really missing. It will be added in the next version within few days. But now you can add it this way:

1. Add Opt Fragment

2. Right click on it and choose Properties from the context menu

3. Switch to Fragment tab

4. Change 'opt' in Interaction Operator box to 'break'

You can add a gate to a sequence diagram using Gate tool in toolbox (it is under Found Message tool).

If you have any other questions or encounter any problem, feel free to let me know.
