 Heynote is a dedicated scratchpad for developers. It functions as a large persistent text buffer where you can write down anything you like. Works great for that 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.

 Heynote is built to support synchronizing the notes library (or buffer file in the case of Heynote 1.x) through file-syncing services like Dropbox, OneDrive, etc. However, note that the synchronization logic is quite simple, so editing the same note on two different machines at the same time might lead to conflicts and unexpected results.
