Hello there, thank you for your contributions 👍

There are a couple of things which have to be improved before I want to merge this into master.

• There is no need for a 'save' button, all modifications are already synced with the model on a change.
• There are typos across the PR with plant: you write planet instead of plant.
• one of the main goals of this app is to keep the UI as minimalistic as possible, while showing a realistic usage of the provider package. many tutorials out there show a too simplistic 'hello world' scenario to demonstrate the provider package. maybe you find a nicer way to integrate the note into the rest of the UI. for instance, if no note is added, you show a red banner with 'add a note in edite' which I think is rather intrusive.

I can look into your changes and try to come up with a better UI integration if I find the time, or you try out more ideas. Nonetheless, many thanks for your PR.
