Lately I've been implementing the last bits of auto-placement algorithm in Blink and WebKit, I even have a patch almost ready for "stack". However, I agree with you, probably the best idea is to come back to "none" (maybe adding again "grid-auto-position" if we think it's needed). Right now I cannot think in a use case for stack algorithm with the 3 "different" behaviours depending on the positions defined or not for the item: * Definite row: It'll use "dense" algorithm. * Definite column: It'll find an empty cell in that column and stack all items of that column there. * Fully auto-placed: It'll find an empty cell in the whole grid and stack all auto-placed items there. My 2 cents, Rego
