Feature request / question regarding browsers and terminals

[Anton Hvornum]

Took me a while to get acquainted with the setup and all the variables.
But once that was done and over with, I started wondering why some configs were taken from the environment variables - and some don't?

Take the browser for instance, it's hard-coded to firefox for whatever reason.

I propose that this:

local terminal     = "urxvtc"
local editor       = os.getenv("EDITOR") or "vim"
local gui_editor   = "subl3"
local browser      = "firefox"
local guieditor    = "atom"
local scrlocker    = "slock"

changes into something like this:

local chosen_theme = themes[5]
local modkey       = "Mod4"
local altkey       = "Mod1"
local terminal     = os.getenv("TERMINAL") or "urxvtc"
local editor       = os.getenv("EDITOR") or "vim"
local gui_editor   = os.getenv("GUI_EDITOR") or "gedit"
local browser      = os.getenv("BROWSER") or "firefox"
local guieditor    = os.getenv("GUI_EDITOR") or "atom"
local scrlocker    = "slock"
