Sprite Importer for Unity has been launched!

This is an essential tool for people who are working with dozens or even hundreds or thousands of spritesheets. Going through and configuring each one for pixel perfection and slicing them one by one is simply not an option for you. 

I understand, and I've got your back.  With this asset, you can create multiple settings files designating specific folders for different configurations and slicing settings. Any sprites you place within those folders will immediately be configured and sliced to your desired specifications within seconds to minutes (depending on how many files there are).  Leaving you more time to do what you do best, developing a great game!
