Node modal

[anovazzi1]

This pull request adds a new feature to the flow editor that allows users to access advanced fields of a node in a modal pop-up window. The modal pop-up is triggered by clicking on a new button on the top-right corner of the node.

The pop-up window contains all of the advanced fields for the selected node, organized in an intuitive and easy-to-use interface. Users can enter and edit data in the pop-up window, and all changes are automatically reflected in the main flow editor.

This feature is particularly useful for complex flows with nodes that have many advanced fields, as it simplifies the user interface and makes it easier to manage and edit the flow. It also helps to prevent clutter on the main flow editor by hiding advanced fields until they are needed.

Strongly disagree, 'advanced' should display in the modal and 'show' in the node. two different things.

But what if we set both to True? I think right now show=True shows in both places.

One idea: what if we only show things that require another node (inputs), and all the rest go into the advanced part?
