The advantage of the Manager that it is easy to use and at the same time very powerful and easy to integrate with the GNOME desktop. Currently Sunflower is under development, but nevertheless, it is fully functional and does not conflict with the main file Manager after installation.
File Manager Sunflower reminds Total Commander in Windows. And it is really convenient to work in two-pane mode, as possible to do copy, move files between the directories or the comparison of two directories. I recommend you to try the Sunflower to see how fast, easy and potential.
I would like to mention the use of the terminal directly and the Manager window, clicking on the terminal icon and it will open in the tab, without having to open an additional terminal window.
Installation latest version into Linux Mint:
sudo add-apt-repository ppa:atareao/sunflower sudo apt-get update sudo apt-get install sunflower python-vte
