These types of "mini-GUIs" could certainly be useful. My point was that
there is no need for a separate "icon GUI" extension, something like
that pretty much requires a complete widget library to be really useful
anyway and the GTK+ extension already supports multiple GUIs per plugin
and embedding them on a canvas or in its own window or anywhere the host
wants it. The only thing needed to distinguish between small "icon" GUIs
and large "editor" GUIs would be some sort of annotation in the RDF data
(that hosts would be free to ignore if they wanted to).
