Feature Suggestion: Merge Preview Image and Save Image into a single node with a 'Save' toggle

[Well-Made]

Right now, there are two output nodes: Preview Image and Save Image, which can be swapped via the right-click menu.
But this isn’t always convenient. If I don’t want to save an image at a given stage, I either have to swap the node to Preview Image, or add a separate Preview Image node and bypass the Save Image one.
My suggestion: merge them into a single node - let’s say Preview Image with an optional “Save” checkbox.
That way, you could preview results at any step in a multi-stage workflow and choose to save them (or not) with just a toggle - no need to keep swapping nodes or toggling them on and off, or clutter the graph with duplicate outputs.
This would be especially helpful in chained workflows where you might want to optionally save intermediate results without duplicating or reconfiguring nodes.
I couldn’t find an existing discussion or feature request about this, so I thought I’d share the idea here.
