Hi,
I’m very, very new to i3 but loving it!
My hand still seems to jump onto the mouse of its own accord tho 
I have most thing working but GParted (gparted) and Gnome-disks ( gnome-disk-utility) arent going full screen when I press F11, as do all other apps I have.
F11 works with other apps without being in the config file
This was handy since I could reallocated mod+f to opening file manager (I come from Archbang most recently).
But since this didnt work for those two gnome apps I inserted an extra mod+F11 bind to use for them.
So, in summary, the config file modifications I had to make to get fullscreen working with all apps was:
# enter fullscreen mode for the focused container
# $mod+f reallocated to exec pcmanfm
#bindsym $mod+f fullscreen toggle
# NB F11 works except for GParted and Gnome-disks, but $mod+F11 works for these two:
bindsym $mod+F11 fullscreen toggle
so now if I want fullscreen for Gparted or Disks I use $mod+F11, but for all other apps F11 on its own works
Could someone please explain to me why this is needed / why F11 doesnt work on its own for those two apps?
I also have the below in config to make Gparted and disks start in Desktop 9, in case it is relevant (but I think not):
(I had to remove “” from assign [class=GParted|Gnome-Disks] $ws9 to get it to work with the pipe bar to include both apps on one line)
(Font Awesome characters not showing here, but are fine in config.)
