After using Feren OS in Parallels for a few days, I'm close to replacing Peppermint OS with it on my PCs. I customized the appearance using a combination of the "Redmond" (included) and "McMojave" (downloadable) themes:
Feren OS is cool. I think it was some college kid who made it. It's very similar to Zorin OS. Funny story, I paid for the premium Zorin... Wasn't bad, but wasn't worth the money. I figured it wasn't much and I wanted to see the difference between that and lite. Nothing to write home about, at the time of testing.
