We should have a standard way (not a plugin) to create visually appealing and customizable selections (tables, carousels, etc.) from lists or saved searches, and display them on the OPAC, on staff interface, as well as outside Koha in the form of an HTML widget. Some other ILSs offer this feature... I never tried this plugin https://github.com/inLibro/koha-plugin-carrousel but maybe it could be a working base.
