Motivation

1. I wanted to make a simple note that could close the editor without saving like notepad++
2. However, notepad++ is only supported on windows (except using Wine)
3. 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.

Update (v1.5.0+): File editing is now supported with an integrated Monaco Editor-based file editor window!
