BackLighter

Don't want the device screensaver to go on and black out the display when using applications like speedometers, timers, etc.? BackLighter prevents just that. BackLighter disables the screensaver from dimming the device while the application is left running and set to ON. The screensaver can be once again enabled by setting the switch to OFF position or by closing the application. BackLighter also allows brightness control with several convenient settings.

This app is developed by bitLite bitLiteApps@gmail.com and still published at Ovi for free http://store.ovi.com/content/224077/. I posted it at my repo for backing up purpose in case when M$ kill Ovi finally.
