Mac: Recent Menu is an app that sits in your menubar and offers up all your recently accessed files, folders and apps so you can get to them quickly.
Recent Menu is simple, but powerful. On the surface it simply shows you a drop-down menu with all your recent files. However, you can set it up so it only shows certain file types, file names, and for select durations of time, which makes it incredibly helpful for specific projects. Macs have this built-in a little with Spotlight and the Recent Items menu, but Recent Menu makes it a lot easier to find what you're looking for right away.
