Merge the flag module with the nodequeue module.

At this time, we have no intention of replacing nodequeue. While both have a node-link for "flagging" (or adding to a queue), they fulfill different goals. Nodequeue deals with putting things into global "lists", in which you can change the order. Flag does not provide the same abilities, as a "flag" is nothing more than a user saying "this thing means something to me", whether that's offensive, a favorite, or a bookmark. The "global" ability of flags makes the lines a little blurry, how it operates in a way similar to a single nodequeue.

Regardless, I think both nodequeue and flag have their own place, and we have no plans to offer "ordering" of items in a list.

It's alright to close this isse?

Who knows, perhaps we'll change our minds. There's an issue dealing with this:

#307839: Support weights

Maybe that "Draggable Views" module could do the work for us.

By the way do you have a roadmap for the flag module ?

A good question. Perhaps we should start a "Roadmap" page. But it'll be a fuss to keep it updated. So perhaps the issue queue could serve as a roadmap.
