The blackout updater is from TeamBlackedOut it allows you to keep up on all their inverted/clear apps...I use their apps because I find them consistently AWESOME.
LMT is pie controls...I really don't use it much but some people swear by it...I'm not much help there. Lol!
Smanager is a great script management app that is needed for the over clocking method in this ROM. See op for the instructions.
Cleanmaster is a really great all around app...task killer...cache cleaner...app manager...and I guess the Devs are working on adding virus and security management.
Hope that helps a bit. Glad you are enjoying the ROM thus far!
Thanks!
