Press This should support post formats

I don't mean to rub it in, but: #14650 :)

All for it. Even at the time I triaged it, it was a bit late for 3.1 though.

We had something like this in 2.5, no?

Patch is missing some important bits that we see in post.php, such as theme support checks.

Per IRC discussion, let's go with a select box as a compromise for 3.1. Otherwise press this can't actually support this in terms of space.

I'm still not sure the POST handler logic is complete.

Looks good. Will review it tomorrow and give it a good tire kicking.

Assigning an owner so we can keep track of who is iterating the final tickets.

Will ask Jane if she can agree to these changes: ​http://cl.ly/350l0S1O3L0M1P1F2U0W.

For reference, here's the 3.0 version: ​http://cl.ly/1Q0u2B2g0C2H1E2y1F0a. (Of note, the publish box could not be moved or collapsed. Removing the redundant title is not the end of the world.)

Patch refreshed with some minor code and UI changes.

Approved and tested.

Fixing some self-closed option elements.

Patch updated against default post formats in #15882.

Just needs final review.

Looks good.
