As part of the application's tabletization, Adobe added this New/Open screen which can display document thumbnails, libraries, or preset new document types and sizes. Personally, I hate the tabletizing of desktop app interfaces -- see all that wasted space on either side?
Happy almost-2016! Adobe finally gives Photoshop users the ability to customize the tools which appear in the toolbar, and you can save them as a preset. All of the tools that you remove remain available in the three-dot tool.
Return of the oil paint filter
When Adobe dropped its Pixel Bender GPU filters, a predecessor to its current Mercury Engine accelerator, one of the casualties was the Oil Paint filter. It's baa-aack, under the Stylize filters.
Automatic library creation
Photoshop can create a library from the assets in an existing document. Unfortunately, it's not smart enough to know that you already created a library from a given document.
Adobe made it easier to quickly duplicate artboards; just click the plus.
Precision placement of type layers
You can now enter coordinates to place type; I miss the ability to enter an offset value in addition to absolute, though.
Type interface improvements
Some nice enhancements include the ability to filter your fonts by characteristic, as well as by Typekit availability; build a list of frequently used favorites; and find similar fonts (the wavy lines).
Somewhat improved Glyph palette
The palette now saves recently used glyphs. It would be nice to have a place in the palette to stash frequently used glyphs as well.
Photoshop's type properties now include filtering by similar fonts. It's nice, though I think its definition of "similar" is a little too broad.
You can now filter all your fonts by class, though only by one at a time. I hope in the future we'll be able to multi-select and that Adobe will add more stylistic and use options, such as fonts that have both Web- and print-licensing, normal versus all caps, body text versus display type, and so on.
There's now a Quick Export option in the Export menu that will save to a user-defined format and quality. That's really useful, at least for me.
Adobe extends control over the appearance of different interface options to Artboards.
You can now turn off Photoshop's default of entering transform mode when placing an object.
Adobe added the ability to batch export in multiple sizes plus a "convert to sRGB" option. I can't find a way to save presets, however.
Fuse poses and animations
When you bring in a Fuse model, either via the libraries or saved externally from Fuse, you have a relatively large selection of preset poses and animations to apply to it. You have some minimal controls over ways to vary both. The palette hasn't integrated the existing Fuse architecture into Photoshop very well -- for instance, you have to page through the options -- but as with most initial implementations, that will probably get fixed soon.
There are preset facial expressions you can apply to a Fuse model, and you can adjust the intensity of the expression, the head tilt on three axes, and the eyeball rotation up and to the sides (for the perfect eye roll). However, if you select a different facial expression from the preset, those remain fixed and you can't keyframe them to change as the body moves. The results can be...odd.
Look but don't touch
You can see the skeletons of the models in Photoshop, but you can't manipulate the bones.
All of the Fuse textures are available for live painting and other typical texture-map Photoshoppery.
