Is there room to expand collapsable nodes outside of just type-converters? For instance:
Other nodes that have one input only (including lists)? For example, Add, Multiply, Spint Off Event/Value...
Nodes where only one input is being sent data? For example, Get Item from List where the List port gets sent data, but Which is entered manually...
Chains of nodes that match the above requirements? For example, say some text data comes into an Append Texts node (with a / separator) to compile the pieces of a URL for an image that will be fed into a Make Image Layer node. The first four nodes could be collapsed in this chain: Append Texts>Fetch Image>Invert Image Colors>Convert Image to Layer>Render Layers to Window (As it is now, only the second last node is collapsed automatically.)
