Me, at 11:00, choosing a new portfolio-building project. 1. Knapsack - Simple, intuitive invetory management for people who lose stuff often. 2. Hashtoast - A space for you and anyone! 3. Eisenhower - A To-do for you. 4. Sine Notes - A notes app that's simply secure 5. Wormshelf - A library management system. Which one should I pursue first?
