You might be overestimating the complexity of creating such a hodgepodge. i3wm = tiling window manager lxappearance = set gtk theme and settings qt5ct = set qt5 theme and settings kvantum more settings for qt ponymix cli for pulseaudio that sucks less than pactl pavucontrol gui mixer nm-applet tray applet that lets you select a different network i3status-rust nicer and more powerful status line for i3bar rofi a launcher that looks like nice and is more powerful To this add all the other apps you already use. The thing about this hodgepodge is that there really isn't much to be said about integration as the different components don't require or benefit from such. The connection between such are so bare direct and obvious that there isn't much of a question how to put it together. You change a line in your i3 config to start a different app at startup or trigger a different one with a keybinding. If you had done so 5 years ago you could be using much the same configuration now and much the same configuration 5 years hence. I guarantee you that whether you use KDE or Gnome or Windows you are liable to spend a day here or there tweaking your environment even if Bob in accounting doesn't.
