Design
Using Figma As a Primary Design Tool
Figma is the new hotness when it comes to designing, particuarly for the web, but for most anything really. It's a Javascript based web based application that essentially supplements (or replaces) a lot of vector based design tools like Sketch, Illustrator, and Photoshop.
Using and Organizing Icons with IconJar
Recently I gave IconJar a try. It's a fairly simple program for Mac that allows you to browse and preview all your icons in one place. Similar to what Font Book or Extensis Fusion is for fonts.
