heynote is a dedicated scratchpad for developers. It functions as a large, persistent text buffer divided into blocks where you can write down anything you like. The software works well for a Slack message you don’t want to accidentally send, a JSON response from an API you’re working with, notes from a meeting, your daily to-do list, etc.
The heynote buffer is divided into blocks, and each block can have its own Language set (e.g. JavaScript, JSON, Markdown, etc.). This gives you syntax highlighting and lets you auto-format that JSON response.
This is free and open source software.
