Hide certain parameters in nodes #2280
Description
Describe the feature / issue
Currently, all Options on a node are displayed in the GUI. However, we might have content in a node that needs to be saved in the TOML file, but doesn't make sense to present to the user. We could add a hidden flag to a parameter that would tell the GUI not to display the parameter, but would ensure that the data is still properly serialised.
