Ideas

when a component refers to several sources (e.g. FieldTransform with n lookups) it would be nice to highlight the "main" source in the flowchart (for instance a bold line)

using a shortcut to get the list of available methods, e.g. you type "API." then Ctrl+Space => the list appears and you can select

Tooltip, for example, in the integrator for the charging modes to explain them briefly. If possible, even with an example.

Hovering over a variable used in an integrator component should give you the current value of that variable. This should work everywhere you can use a variable, including the flow chart.
