We are planning to add universal approach to control this option for all rooted phones.
Holo design is a top change on our list as soon as we stabilize SP on ICS+. we will use ActionBar sherlock to support older OSes out of the same codebase.
SP has "notify" action where you can setup ringtone and/or vibrate for a period of time.
A rule can look like:
If silent profile activate and on a meeting, notify with ringtone (shortest should be selected) and notify with vibrate for 20 minutes.
Hope it helps
((@home OR @work) AND Charging) OR @cinema AND Have_wired_headset_connected is the same as
(@home OR @work) AND Charging OR @cinema AND Have_wired_headset_connected.
Additionally you can regroup conditions by drag and drop. We try to avoid complexity in setting boolean conditions and guess it would be hard to inject parentheses into current UI, however technically it's easy, UX friendly UI is the question.
