I'm sure Brian will weigh in on this topic.
For me, I've used LL where the client only has control of it on touchscreen UIs, so YMMV.
Definitely Enable the LL on each Global Preset.
I believe that you have a scene on a button (Hardware or virtual) without checking the LL on that button, you can now just P+H for ~ 5sec. and the? scene will be updated.
You'd of course need some way to change the levels appropriately, which is why I only use TSW/iPad for this as if is a better user experience...
