Yesterday I came across a nice detail, by accident: When you begin to drag an interaction noodle, if you hold the OPTION key on Mac while dragging, the interaction will change into a Swap overlay interaction. This allows me to create Swap overlays very quickly indeed.
Why not add more of these, for instance holding SHIFT could make it a Open overlay interaction, etc. In that example, the interaction settings popover would still open because Open overlay has a number of options I may want to tune, but at least the interaction type (Open overlay) would be already set in the dropdown.
Those are tiny details, but we do those actions millions of times a day…
