HowTo: Change the default terminal from st to gnome terminal

1. Install gnome-terminal (or whatever terminal you prefer): sudo apt install gnome-terminal and Stage your own i3 config file.
2. Remap the i3-wm config to launch gnome-terminal instead of st by editing ~/.config/regolith/i3/config and changing the following line: From: bindsym $mod+Return exec st To: bindsym $mod+Return exec gnome-terminal
3. Save file and reload i3 with ⊞ Win-shift-r
4. (Optional) Update your system to default to your terminal of choice by running sudo update-alternatives --config x-terminal-emulator (See this page for more details)
