I´m looking for a way to present information (simple text) that can be typed into a panel with text input. The panel is active on the session but it will be displayed on the 3D viewport all the time.
Like this:

On softimage we called these "notes" and it was an extra item on the collection. I don´t know where to start looking, since the original code is not part of Blender for doing this. I used this function a lot in softimage. Please help. Thanks.
