ONE GOOD FREE FILE MANAGER
I am angry and pissed how not a single free open source file manager, actually made for power multimedia users, has been made to date with the ideal functionality I can imagine. Not even free closed ones are good enough. And not even paid ones are what I want them to be.
Linux file managers all have a problem of not having attribute detail columns related to videos, audio and photos for some bizarre reason. On Windows you have Explorer++ and FreeCommanderXE, best ones, that screen tear like a bag of poop with thumbnails on, then you have Directory Opus which costs $80 and still is not ideal because all they figured out was giving options, but not getting experienced power users to help design default UIs.
