What desktop or window manager you mostly use and why.

[sacman08]

I have been a long time Xfce4 user and then have Fluxbox as my backup wm, but I am trying out GhostBSD and I am enjoying using MATE.

I use:
1. Mac OSX El Capitan;
2. LXDE on Ubuntu;
3. KDE on FreeBSD;
4. Mate on GhostBSD.
Everything for development (web, mobile and desktop).

To me, DEs are out, if a window manager has its keybindings convoluted (read openbox), is out. I cannot waste time going to menus and clicking. Not to mention the RAM waste, thus, speed is where is at; looks mean nothing to me.

JWM, Icewm, and Ratpoison.

xfe -file manager
mirage -image viewer
nano -word processor (save everything in .txt)
scrot -take snapshots
flburn - burn isos (small and simple)
hexchat
xdgmenumaker - includes menus for JWM, menumaker does not.

On linux, any distro, for me it has to be Cinamon.
Most used apps, again on linux: FireFox, Thunderbird, Geany (lightweight gtk editor), Transmission (torrenting). Although most of my time is spent on the command line.
