the only problem I have with lightflow is that it takes complete control of the LED and doesn't permit other apps to control the LED. E.g. I use touchdown email and TD allows it's own LED control. Lightflow does not support Touchdown so it not only does have LED notice for TD but it also blocks my TD from using the LED. If there was a way of providing other apps to "override" the Lightflow (maybe by specifying them from a list), then I would even pay for the Lightflow version. I have requested that the developer provide support for TD.
