🎨 App Icons: 130 designs to choose from, in Settings › Tweaks.
📅 Calendar export, fixed: removing exported doses no longer crawls or trips your calendar's "too many deletions" warning, and newly exported doses show up in about a minute instead of the next day.
✅ Logged doses now land on the day you actually logged them, not the day they were scheduled.
