Unity’s Previews feature has seen a number of refinements over the last week as work on Unity in 13.04 continues.
A slicker animation has been introduced, along with better visual differentiation between the active and inactive preview items.
Most notable thus far is the new ‘drop-down’ animation when opening a preview. Although not quite as ‘interesting’ in action as that used in 12.10, it is faster and cleaner. Preview details themselves now appear within a container to better differentiate the details pane from general icon grid.
Following that thinking, the container also adds a small ‘call out’ item pointing to the icon, file or item being previewed and ‘ghosts’ (turns into darkened silhouettes) the icons of items not being previewed.
