One way to start designing an application is by creating mock-ups of the user interfaces. This way, you can present your mock-ups to your stakeholders, discuss them, update your mock-ups accordingly, and resubmit them to stakeholders. This can be done before you start developing.
The EveryNote app will look like the following mock-up:
The application will have the following features:
- Create new notes
- Show all notes
- Update an existing note
- Delete a note
- Save notes to LocalStorage
After basic features are implemented, we will also add two more features:
- Search among notes
- Pin a note
