Improve openpad note application by implementing "read only" and "encrypt file" features

Components

Openpad note is a simple text field android note application use for noting important information for future use and other reasonable purposes.

Proposal

Read only feature help keep users notes safe because if a note is set on read only option, it can't be edited.
With this feature, users notes can't be edited by unknown person without the device owner's consent.

Encryption feature" is very important on any note application. This feature ensures that saved files on this application are secured and can only be accessed by the owner because he/she has the code to unlock encrypted files.

Benefits

Availability of read only mood option is important because some important notes saved by a device owner can't be changed or edited by another person apart from the device owner. An encryption feature will really improve this application and make it a trusted and reliable note application, as users files will be secured and only be access by device owner. Openpad note application will be one of the best note application if my suggestions implemented.
