Components
Boostnote is an open source project. It's an independent project with its ongoing development.. it is a note-taking app for programmers that focusing on markdown, snippet and customizability.
Proposal
Having studied the app and also gone through it thoroughly, I noticed that it has no share option for users to be able to share notes to people either on whatsapp or gmail.
Mockups / Examples
New look of the interface
Benefits
The main benefit of the share feature is to enable users of the app to be able to share their notes with friends as this could be a means of writing down answers to an assignment and sending it directly to your lecturer through email sharing which will be part of the share option.
