A quick and simple dashboard with holoviews and panel to sort images into categories.
The logic of sorting is implemented in Server class and seems solid. The desired interaction between panel elements is defined in Client and it is lacking. Particularly it was build around idea of filenames moving from one pn.widget.Select to either of a number of target Select widgets (all callable and allowing to select an image). Unfortunately, none of the Select areas ever updates its options so the panel looks a little sorry for itself, yet works.
Perhaps, Client could have been perfectly suitable for a subclass of param.Parametrized 🤔
