Components
Drawable-notepad is a note taking app with additional feature of drawing and scribbling on it.
Proposal
I would suggest the app gets to have a means of making the users save their data either locally or online. This could be in form of local backup and restore options on the phones storage, or a synchronisation with an online database.
Also the need for a dropdown menu from the menu bar which would contain relevant settings and options.
Mockups / Examples
Benefits
Having such a feature would provide the users a means of having a copy of files somewhere and this could be of good use when changing devices or if it's an online sync, previous data from the user can be recovered in case of loss of phone.
The app would also be more useful with some added settings and looks would be improved.
