Agree.

I meant this. Perhaps an extra dialog showing the tree-character of boolean
expressions (with the ability to refactor them) would be cool.
[&&]
[!] [!]
(a) (b)
or
[||]
(a) (b)

I believe, they would be *very* helpful, because a lot of complex boolean
expressions cause a lot of bugs. Transforming them to better readable form
lets you easier find bugs.
