The Team Win Recovery Project has been on a roll lately, adding several new features including auto screen timeout and built-in SuperSU flashing in the 126.96.36.199 update just a few days ago. Things are getting even better, as XDA Recognized Developer Dees_Troy and team have just released the 188.8.131.52 update that brings even more improvements, bug fixes, as well as a couple of new features to TWRP.
File selectors and list boxes now have a scroll bar to help you navigate their contents. Also, the recovery now uses libblkid to detect file systems more accurately, getting rid of problems with exFAT partition detection. Aesthetically, there’s now a screen dim effect on some devices that appears two seconds before the screen times out.
When it comes to the bug fixes, mknod failures and issues with restoring hardlinks when restoring backups have been taken care of, and your backups should now restore correctly. File selector crash, screen timeout loading during startup, and military time persistence problems have been fixed as well. The screen timeout code has also been optimized and some other bugs have been ironed out.
You can read the official change log and find links to device-specific forum threads for downloads and more information in the TWRP Touch Recovery Device master thread.
