I like the Pantheon file browser from Elementary OS. But it also doesn't have the "file preview" that Finder does, and I haven't had any luck trying to get Gloobus Preview working with it.
I noticed that the new ElementaryOS came out just a few days ago. Always wanted to give it a go but haven't had the time. I'll try it in a VM one of these days. Thanks for pointing me ta their file browser... had no idea they put so much work into it.
