Building on written code

I have another application idea where I can re-use a lot of the code from Initiative. I’ve “mastered” the list and custom dialogs. So I’m moving on to Is It Open?. This application is another list widget, but will require database storage too. I’m planning on building it without the database storage first. While I was building Initiative, I changed list item model a lot. Once I’m happy with the models without permanent storage, I will then work on saving them to a database.
