4.1: Call for Tickets

What tickets would you like us to look at in 4.1? (Extra points if it already has a patchpatch A special text file that describes changes to code, by identifying the files and lines which are added, removed, and altered. It may also be referred to as a diff. A patch can be applied to a codebase for testing..)

Since the release is officially underway, now is a great time for us to prioritize work and make sure our pet projects/tickets get some airtime. The priorities of the community matter. Let us know below what you would like to see in WordPress 4.1.
