Testing the new feature --- on-demand; it's a great feature!
It seems to me, an extension without its icon (e.g., conky) can be fired directly by clicking it on the on-demand list. But with its icon (e.g., shiretoko) it will be not be fired; but displayed on the wbar. It takes another clicking to be fired.
Could it be possible to have single clicking on-demand items (with or without icons); keep them away from the wbar?
