Operator IO is undergoing the following changes and upgrades:
- Hiding of inputs - They don’t show in the graph (unless wired up), but do show in the property panel.
- Visibility modes - There is some case for defaulting to hiding all unused inputs and reserve some for advanced use only.
- Auto-expansion - Multi-input operators are grouped together into a single operator type that offers variable number of inputs, and a + prompt input to trigger expansion.
- Type switching - Operators supporting multiple input data types can be automatically selected based on the first input or output connected.
With these improvements a number of new operators will be added, e.g. Select.
