I could write a whole book about this project and what i had to go through to get it out but finally I think its there.
Ghostnote allow you to add notes to almost anything on your mac. Files, folders, applications, websites and even documents open inside applications (ex a photoshop document).
I made it because I am not good at structuring and often just need notes for specific context but soon realized that this approach actually has quite a lot of potential.
Next update will have support for applescript so you can customize context.
Let me know if you have any kind of feedback. Everything is appreciated.
