[Feature request][API][Frontend] Extension of the API for hiding widgets and outputs

### Feature Idea

Guys, big request: please extend the JS API and add simple methods that allow us to hide node widgets and outputs without various hacks. Ideally, this should work without reindexing inputs and outputs.

Right now, it’s almost impossible to hide a node’s outputs properly. Yes, I can destroy them and recreate them, but that only “works” visually — Python then ends up sending incorrect data.

It would be very useful to have straightforward methods for visually hiding inputs, outputs, and widgets.

Thanks.
