* persistence step 1 * fix build * messages in the background work, notifications not yet * app state store * DM icon shows up * notification launches when app is closed! * keep ui updated * lifecycle fixes * extensive logging, maybe revert later * send nickname in announcement * quit in notification * setting in about sheet * fix quit bitchat * lifecycle fixes * power mode based on background state * stats for both direciotns * fix graph persistence * better counting * count per device * only compute when debug sheet is open? untested * fix read receipts * fix read receipts fully * fix unread badge if messages have been read in focus * foreground promotion fix * fix app kill in notification * adjust to new tor * nice * about sheet design
