Action pane UX: containers identification

[pjjr]

In some cases, not even too complex, in data structure viz, it's hard to follow which line belongs to which container.
Some of these would be very helpful:
a. collapse all button at the top
b. different background or vertical line color for odd/even container (1%~2% darker)

• background color is hard to imagine; losing of the simple flat design is in risk
