 - **Port the UI layer** (~1 single-file MoneroScreen.kt that was ~1958 lines in Garnet, ported to Amethyst patterns)
   - Challenge: Garnet used Material3 standard Icons (Icons.Filled.Edit, etc.) but Amethyst uses custom MaterialSymbol system
-  - Need to adapt icon usage to Amethyst's `commons.icons.symbols` approach
-  - Need to add missing string resources (daemon*, monero_fund*, backup_seed*, transaction_priority*)
+  - String resources already added (daemon*, monero_fund*, backup_seed*, transaction_priority) ✓
+  - Need to adapt icon usage to Amethyst's `commons.icons.symbols` approach or use androidx.compose.material3.icons.Extended
   - Need to use Flow-based state collection instead of LiveData
 - Add NIP-69 monero address support
 - Full build verification (`./gradlew assembleFdroidDebug`)
 - Test monero wallet functionality
 
+### Known Issues & Gotchas
+
+- **Material Icons package**: Amethyst doesn't include `compose-material-icons-extended`. Either:
+  - Add the dependency and use `androidx.compose.material.icons.Extended.*`
+  - Convert to `MaterialSymbols` from `commons.icons.symbols` (preferred pattern)
+- **TransactionDirection** enum is in `com.vitorpamplona.amethyst.model` package
+- **TextSpinner** is in `com.vitorpamplona.amethyst.ui.components.TextSpinner`
