Shouldn't 'analytic' and 'starter prompts' also move into this dialog?

[0xi4o]

Sure. I can move them 👍

It would be better to add a JSON configuration item, which can be accessed by $config.xxx(similar to $vars.xxx) and override by RESTful API calls.

I used the flow configuration to switch database_name or API url etc.

Currently, I do it by addding a FlowConfig node.

But, this seems not a good idea.
