In Exhibition/Events Time tab: possibility to select days and times, not just times!
A custom field to add page header background for post types archives like ?post_type=Exhibition, ?post_type=Artworks, ?post_type=Events, ?post_type=Venues…etc.
The Exhibition/Events list/grid Widget should have possibility to show all elements, not only Past or Future.
IMPORTANT! A widget to select, search and filter by Category, Tag, Custom Taxonomy, Post Type, Post Date or any combination of these easily to really refine searches in Artworks.
(Example. i have tons of artworks. A good search filter should let me select all artworks in category “Drawings” with Tags “animals” and “nature” ).
In the Single artwork it would be good to find arrows to navigate next and previous artworks.
In Artwork List/grid Widget add a filter to Order by date, name, Random!
