A few general WebCore questions that I couldn't find in the wiki

[HAL2000]

1. In the WebCore Home (Dashboard), what do the true/false mean next to the names of my pistons?
2. How do you delete superfluous nesting to neaten up a piston? (see purple circles in screen shot)
3. What do the blue, red, and green lines mean when viewing a piston? Red seems to mean that the condition is false, green seems to mean that is is (or was recently) true. Blue??? (see green/blue arrows in screen shot)

1. In the WebCore Home (Dashboard), what do the true/false mean next to the names of my pistons?

last piston state which defaults to true when executed unless explicitly otherwise by the piston on exit.

2. How do you delete superfluous nesting to neaten up a piston? (see purple circles in screen shot)

click on the opening bracket in edit mode then click delete in the popup.

3. What do the blue, red, and green lines mean when viewing a piston? Red seems to mean that the condition is false, green seems to mean that is is (or was recently) true. Blue??? (see green/blue arrows in screen shot)

that section of the code was executed on last execution. shows gray if a section of the code was not executed because the enclosing condition was false.
