In this tutorial, we learn how to sync preferences with DropBox or Ubuntu one. This doesn't work for everything, but it will sync pigeon preference. It's a folder ".purple" and all the preferences are inside here. If you are familiar with using command prompts, then this will be very easy for you to do. Make a symbolic link from the command prompt to the drop box folder. On every folder, you will get the same result! This is very easy to do and just takes a few seconds to find, then you can change up the preferences in your computer and sync them as well!
