I am evaluating if I could use RB on my htpc but I cannot understand some things:

First; is it possible to launch 2 behaviours. Like starting safari and activating virtual mouse at once and then have the vm to disable once another application is started?

Second; I was trying to create my own actions and behaviours but found out that I cannot use RB's built-in actions in custom behaviour? When creating new action there are some RB-actions that I can call but not all of them (e.g. my list was missing mac blu ray player) are present.

Am I missing something obvious?
