middle-click on the "preset" icon to open the menu could work
To create a new instance for a given preset, the flow is currently:
1) Left-click on the "preset" icon to open the menu
2) Middle-click on the entry to create the instance
This leads to a weird finger movement from the left to the middle button. It would be nice if a middle click worked in step 1) too, so that we could use the same finger movement twice.
