Disable Gesture Area LED when an app is active
When the physical button on the original Palm Pre was replaced with a virtual capacitive button on the Pre Plus, there was more than just a change to the physical appearance of webOS phones. While both the physical button of the Pre and the capacitive button of Pre Plus performed the same functions to minimize cards or provide blink notifications since webOS 1.4, the LED light of the Pre Plus would also light up any time an app was open and active on the device. This may be a nice reminder that the LED light also doubles as a home button, but it can also be quite annoying. All webOS devices since the Pre Plus has continued this functionality, with no way to disable it if you would rather not have the LED light up whenever you are working in an app.
Not willing to take no for an answer, the webOS homebrew community stepped up and provided a homebrew patch to fix this issue. All you need to do is install the "Disable LightBar" patch from developer Herrie and that default behavior of the LED will now be disabled. It will still blink for any app notification, it just won't light up every time you are working in an app.
