I'm so used to widget locker where you can do it. May have to go back to that but not sure if you can get the stock miui lockbar to work with it, as that is rather cool also.
Hey,
I kind of gave up on miui as i almost wrecked my phone trying to get it working just before i went on holiday, about a day before i found out my passport had expired. Needed to concentrate on other things.
Decided to give it a try yesterday and managed to get it working, not quite sure...
