From Flying Meat:
Built on a foundation of simplicity, Acorn eschews the outmoded "many palettes" design from yesterday's editors. Acorn presents a fluid new interface that will be familiar to users of Apple's iLife applications. Designed for simple editing, Acorn features flood fill, gradients, vector shapes, drawing and erasing tools, and more. It also brings a few new tricks to the table, including chaining filters and easy image and canvas resizing. From quickly adding text to an image to creating a new graphic with pixel-precise control to just sketching out ideas, Acorn is great for all kinds of image editing.
What's new in this version:
- Fixed a crasher that would sometimes occur when using the eye dropper tool w/ the option key down on a bitmap layer.
- Fixed a problem where some types of RAW images were showing up black in 10.10.
- Fixed a problem where Acorn thumbnails weren't showing up in Finder list views.
- Fixed a crasher when using the instant alpha tool.
