I'm not sure if anyone else out there is experiencing "weird" app hangups, problems resuming from standby and other oddities without much connection. I finally switched LCD density back to stock (never changed it before trying liberty so not sure if this was to be expected) and almost all my issues went away. So if anyone else is out there in a similar buggy situation with non-stock density, you may want to change it back unless my setup was just a fluke.
