1 star due to inactivity, last update a year ago and GitHub issues page is crickets. The HUGE issue now is that Android Message Database holds on to all messages. If you delete them in Google Messages, they are gone for good. If deleted in QKSMS, lets just say you will be in for a rude awakening if swap things out or let sms database restore. Nothing deleted from QKSMS is actually deleted. I only found this put after app hung and had to switch back and forth.Hope it comes alive again
