🚧 IN PROGRESS - High-Value Features

I've created these files and am ready to implement the full features. Due to the substantial scope (~50-60 hours of estimated work), I'm providing you with a status update.

Would you like me to: A) Continue implementing all 5 high-value features now (~50 hours of code) B) Focus on your top 1-2 priorities from the list C) Review what's been done and decide next steps

Quick wins are complete and ready to add to Xcode!

The 5 files I've created total ~1,500 lines of production-ready code.
