I have been in the same spot. Good to read that I’ve been able to help out. Have fun with this in combination with your gaming!

I use a gaming-mode for that. Like this:

# Create a gaming mode
mode "gaming" {
    # switch to workspace
    bindsym $mod+1 workspace number $ws1 ; mode "default"
    bindsym $mod+2 workspace number $ws2 ; mode "default"
    bindsym $mod+3 workspace number $ws3 ; mode "default"
    bindsym $mod+4 workspace number $ws4 ; mode "default"
    bindsym $mod+5 workspace number $ws5 ; mode "default"
    bindsym $mod+6 workspace number $ws6 ; mode "default"
    bindsym $mod+7 workspace number $ws7 ; mode "default"
    bindsym $mod+8 workspace number $ws8 ; mode "default"
    bindsym $mod+9 workspace number $ws9 ; mode "default"

    # move focused container to workspace
    bindsym $mod+Shift+1 move container to workspace number $ws1
    bindsym $mod+Shift+2 move container to workspace number $ws2
    bindsym $mod+Shift+3 move container to workspace number $ws3
    bindsym $mod+Shift+4 move container to workspace number $ws4
    bindsym $mod+Shift+5 move container to workspace number $ws5
    bindsym $mod+Shift+6 move container to workspace number $ws6
    bindsym $mod+Shift+7 move container to workspace number $ws7
    bindsym $mod+Shift+8 move container to workspace number $ws8
    bindsym $mod+Shift+9 move container to workspace number $ws9
    bindsym $mod+Shift+0 move container to workspace number $ws10
}

# Enter the gaming mode when a game is started
for_window [class="^steam_app_"] move to workspace $ws10; workspace $ws10; mode "gaming"
for_window [class="^hl2_linux"] move to workspace $ws10; workspace $ws10; mode "gaming"

This automatically moves (most) games to workspaces 10 and switches to that workspace. This allows me to use key combinations that would otherwise be used by i3.

That should be easily solved with: sudo apt install curl
