2. bumblebee-status -> bar for i3 - "https://github.com/tobi-wan-kenobi/bumblebee-status"
3. rofi -> window switcher, application launcher. I'd recommend reading and learning about it - "https://github.com/davatorium/rofi"

5. nitrogen -> to select a wallpaper
6. qt5-gsettings -> to configure QT application, themes, and styles
7. lxappearance -> to configure GTK application, themes, and styles
8. Konsole -> Terminal. you can use anything you want, but for me I like Konsole. [KDE application]
9. xfce4-power-manager -> Power Manager. You need it for battery and sleep configurations and management
10. blueman -> Bluetooth manager
11. xorg-setxkbmap -> to change language layouts
12. picom-ibhagwan-git -> X compositor with blurring and rounded corners features
13. ark -> QT Archiving Tool [KDE application]
