Currently, it's rather unclear what are the best practices for using the timeline, state transitions and managing them. The following features make using the tool very complicated:

• States, state transitions, state property changes.
• Possibility to create 1 or more timelines, and one or more animations per timeline.
• Creating property changes + timeline animation in a state. What to expect?
• State transition editor adds more complexity to the mix. Also seems to produce bloated code.

The usability of those features should be rethought if we can make them easier.
