The media changes are a welcome addition, but I can't help but feel Wordpress is still lacking in the media department quite a lot. One feature I've been hoping for in terms of media management is folders to organise media instead of paginating pages of all images being displayed which usually involves duplicates being displayed. I love Wordpress, but it would be great to be able to upload specific images for example of dogs into a folder called, "Dogs" and then being able to browse and manage media in said folder.
It's great to see Wordpress is taking steps in the right direction with every release. Another wishlist feature would be the integration of the Advanced Custom Fields plugin straight into the core which allows you to add custom meta boxes and fields to posts in a tasteful and aesthetically pleasing way. I'm excited about the future of Wordpress, it's my bread and butter and I don't see it being beat any time soon.
