Hi Noah,
when you access the properties of any object you created (e.g. connection, credential, task etc.), you can assign notes to the object, as seen in the following screenshot:
Alternatively, you can add an object called 'Information', where you are also able to add notes and access these via the Navigation bar:
I hope this helps, and let us know if you need anything else!
Noah
It would be nice to be able to have a tab with a notepad opened where we can take notes
