 ## [Unreleased]
 
+### Changed
+
+- The pagination alignment design property now offers Left, Center and Right, and is applied above and below the gallery. Aligning the pagination moves the selection count or the load more button aside so both stay visible on the same row.
+
 ### Fixed
 
 - We fixed an issue where the Gallery widget could crash with an "invalid attribute id" error when a stored sort order referenced an attribute that was no longer available. The widget now falls back to the default sort order instead.
 
+- We fixed the pagination alignment design property, which had no effect on the position of the pagination controls.
+
+- We fixed an issue where custom pagination widgets always rendered below the gallery, ignoring the "Position of pagination" setting. Selecting "Above grid" now renders them above the gallery, and the page editor shows them in the same place as the running app. With "Both" selected, custom pagination widgets render once, below the gallery.
