835986 - Animate tiles as they are being filtered

Status: RESOLVED INCOMPLETE

(Firefox for Metro Graveyard :: Theme, defect)

Description

[Frank Yan (:fryn)]

While tiles are being filtered in an autocomplete or search view, they should animate into or out of view (via opacity, height, etc.) and, if feasible, between columns, e.g. by sliding through the bottom of one column and into the top of the adjacent one (via CSS3 columns).

Moving to Part II story as animation in the startUI XUL panels is currently too janky to appreciate or evaluate this. 

Also, as the richgrid widget currently conflates model with view (data items == dom childNodes) and a node must be in the DOM in order to be animated, we risk making all insertion/item removals async if we animate filtering. That's a non-starter, so I think we'll need to decouple grid state (number of items and their data) from the DOM representation which we render and animate.
