Cons
Con Buggy
Was missing basic network connect features when Loki launched.
Con Not very advanced
Pantheon files (like Elementary OS itself) does not offer many advanced features since it's mostly aimed at beginners.
Con Unstable software, not a file-manager
really, really dangerous stuff.
Crashes and take your work/files into the nowhere - aware.
Con Not intunitive
In some instances it is impossible to create a new folder. There just isn't right-click option or icon for it anywhere.
Con Distro-specific
Kind of in between nautilus and pcmanfm.
Con Extensions not supported
Currently it does not support script extensions. It would be more useful having plugin to integrate with Dropbox and git.
Con Lack of compact view mode
No compact view with small icons, labels to the right, and multiple dynamically sized columns. This is a standard UI idiom. What is their rationale to not support it?
