Hey everyone, new build with two small improvements: Smarter Notifications: Daily and pack reminders now only schedule if there are actual cards due to review (no phantom notifications when you’re all caught up or suspended). Pack-to-Card Deep Search: You can now search for any card content or deck right from the home Packs screen. Tapping into a match carries your search query all the way through to the card view. Give it a spin and let me know if anything feels off.
