Settings for i3-gaps

# Set inner/outer gaps
gaps inner 10
gaps outer -2

# Additionally, you can issue commands with the following syntax. This is useful to bind keys to changing the gap size.
# gaps inner|outer current|all set|plus|minus <px>
# gaps inner all set 10
# gaps outer all plus 5

# Smart gaps (gaps used if only more than one container on the workspace)
# smart_gaps on

# Smart borders (draw borders around container only if it is not the only container on this workspace)
# on|no_gaps (on=always activate and no_gaps=only activate if the gap size to the edge of the screen is 0)
# smart_borders on

# Press $mod+Shift+g to enter the gap mode. Choose o or i for modifying outer/inner gaps. Press one of + / - (in-/decrement for current workspace) or 0 (remove gaps for current workspace). If you also press Shift with these keys, the change will be global for all workspaces.
set $mode_gaps Gaps: (o) outer, (i) inner
set $mode_gaps_outer Outer Gaps: +|-|0 (local), Shift + +|-|0 (global)
set $mode_gaps_inner Inner Gaps: +|-|0 (local), Shift + +|-|0 (global)

Workspace names

To display names or symbols instead of plain workspace numbers you can use something like: set $ws1 1:mail and set $ws2 2:.

set $ws1 1
set $ws2 2
set $ws3 3
set $ws4 4
set $ws5 5
set $ws6 6
set $ws7 7
set $ws8 8

Use Mouse+$mod to drag floating windows

floating_modifier $mod

Back and Forth

workspace_auto_back_and_forth yes

Application Specific

Open applications on specific workspaces

# Matlab Figures
assign[title="^Fig"] $ws6
for_window [title="^Fig"] layout tabbed
assign[title="^HG_Peer"] $ws6 # Name of window when export figure with matlab

Open specific applications in floating mode

for_window [title="File Transfer*"] floating enable
for_window [class="GParted"] floating enable border normal
for_window [title="i3_help"] floating enable sticky enable border normal
for_window [class="Lightdm-settings"] floating enable

Scratchpad

# move the currently focused window to the scratchpad
bindsym $mod+Shift+BackSpace move scratchpad

# Show the next scratchpad window or hide the focused scratchpad window.
# If there are multiple scratchpad windows, this command cycles through them.
bindsym $mod+BackSpace scratchpad show
