Faster logging, still fully offline: • New: press and hold the Niah icon on your Home Screen for a one-tap shortcut straight to today's entry — no need to open the app first. • Fixed an issue where tapping into a note or date field could unexpectedly zoom the screen. • Each tab now opens at the top — Home and Settings no longer pick up where another tab's scroll position left off. • Fixed a Discreet Notifications reliability issue that could affect the Lock Screen widget after logging today's entry. • General polish and reliability improvements.
