I would like to share with you my MXFB config I have been using with pleasure since a few months. Main things are :
- tint2 simple taskbar at the bottom, not to take too much space. 4 customized executors to have a look at : RAM, proc temperature, battery, and wifi.
- a simple "bar" conky at the top, to have some more details on the laptop if needed. From ceeslans' model, thanks !
- of course the fluxbox menu, made to my liking. With app menu and some other convenients shortcuts for me.
- rofi for both app lauching (F1 shortcut) and file searching through my "rsearch" script (F2 shortcut). Last to be seen on the first picture :

A second one with xfce4-terminal in drop-down mode (easy gesture shortcut on my laptop fingerpad), rofi as an app launcher, and the wifi panel popping up when I click on my "wifi executor" in the taskbar.

Hope that could be of interest for some of you !
