How can I name desktops/spaces in El Capitan?
This is something that I wanted for ages, so I finally got around and built an open source solution!

It behaves similarly to TotalSpaces in that it uses SIMBL to hook into the display functionality, and uses an application with a top menu bar button to rename the desktops.  To install it, just head over to my GitHub and follow the installation instructions!
