I start working on the callerxUI tomorrow, and here is the list features I have in mind for: Edit blacklist/whitelist File location chooser for the list. Mode switcher Start/Stop Timed Activated list (This will take awhile, so it may not be in initial release). If anyone has some other features in mind and wished to be included, please let me know. sms blocker, there's already an app for that in this forum.
