Light Flow is the kind of app that best showcases Android's sensibilities: esoteric, amazingly customizable, and downright impossible on other platforms. The popular notification manager for devices with LED indicator lights has just had a big update to version 3.8, most notably bringing support for the popular NinjaSMS texting app. NinjaSMS users, make sure you're running the latest version of both apps, and enable Light Flow in the settings menu.

Other changes to Light Flow include a tweaked notification system, in which persistent notifications are more, well, persistent. Devices running older versions of Android will have to do without persistent notifications, for reasons which the developer does not list. Users of later versions of CyanogenMod and ROMs based on CyanogenMod should see fewer issues in version 3.8, and more complete support for Google Hangouts (including the myriad types of notifications within the app) has been added.

Light Flow is downloadable on Android 2.2 or later. The free version is limited in its notification support and speed, while the $2.49 paid version supports over 600 types of notifications for apps and settings.

Reworked persistent notifications

New "clear notifications style" of "phone unlocked"
