It doesn't do any crazy ricing, as I mostly focused on usability tweaks and automatic installation of my must-have extensions. (Tiling, clipboard manager, dash to dock, desktop icons)

Most notable tweaks include:

• clicking on a running app minimizes it
• clicking on a group of apps brings up their previews
• adds minimize, maximize buttons to windows
• installs flatpak, adds flathub
• install flatpak and snap plugins into gnome-software (doesn't work on Fedora)
• installs snap
• installs mtp-tools and gvfs-backends on Debian to be able to transfer files from a connected phone
• adds right click > New File
• Super + Shift + S brings up the area screenshot
• Super + E opens the file manager
• Ctrl + Alt + T opens the terminal

(Those already configured on Ubuntu don't get configured again, obviously.)

I also recorded a short showcase to prove that it works without errors https://youtu.be/xf739ivb9hg
