I'm not even so worried about the pain of building, but about how you
can make something that feels good and intuitive to use given the
limited HID data you get from Pd. I mean there is no way to detect
hovering or a mouse key release. I made menu widgets that required the
user to keep the mouse key pressed while dragging, thus scrolling
through the list of available items to pick. Number boxes and sliders
work also with dragging. Nowadays, I'm starting to believe that
dragging with mouse key pressed is not an ergonomic action and I'm
going to avoid it whenever possible. Both, [jp.menu] and
[dropDownMenu], do the selection with two clicks. I think that is the
better approach.

Thanks for the pointer. I certainly will try it out when exploring Purr
Data the next time.
