In addition to my top 5 favorite features (see video below), these little gems certainly help my workflow.
1) Load Swatch Files from HTML, CSS or SVG Document – use the flyout menu on the Swatches panel to choose Load Swatches. Then, navigate to any HTML, CSS or SVG document and Photoshop will find all of the colors used in that document and load them as swatches.
2) Support for Larger JPEG files – now save JPEG files up to 60,000 x 60,000 pixels.
3) Reposition Paths While Drawing – this one is subtle, but also really powerful. When drawing with the pen tool, pressing the spacebar will allow you to reposition the anchor point – while drawing. The key is that you have to still have the mouse-down for the spacebar to work. Otherwise you get the Hand tool (as expected).
3) Recent Files List – up the limit the “Recent Files” to 100.
4) Smarter Selecting of Layer Names- Photoshop has gotten smarter about the way it names layers when merging them. Instead of always taking the top layer’s name (in the group of layers to be merged), if any of the layers that are going to be merged have been manually renamed (i.e.you renamed them), Photoshop will keep that custom layer name and use it as the new merged layer name. As you can see in the screen shots below, when merging the three layers on the left, Photoshop 13.1 used the custom renamed “Rock” layer as the new merged layer’s name. In previous versions the merged layer would have been named Hue/Saturation 1. Note: if you have created custom names for multiple layers that are all being merged together, then Photoshop will take the top-most custom named layer.
