# Leavepad
Leavepad is a multi-platform notepad focused on writing memos with an integrated file editor powered by Monaco Editor.
## Motivation
1. I wanted to make a simple note that could close the editor without saving like notepad++
1. However, notepad++ is only supported on windows (except using Wine)
1. I wanted a memo application that could be unified to the same usability on multiple platforms.
Therefore, I decided to create a memo application by Electron for my own use.
## Features

- Delete all notes
