I use waybar, with:

• date and time
• weather
• workspaces
• tray
• media player
• local IP address
• download bandwidth
• RAM and CPU usage
• bluetooth status
• volume
• microphone usage

I have a sway workspace indicator on the left, the right side has:

• Monitor brightness
• Volume
• Local IP address
• CPU temperature
• Keyboard layout
• Local date and time
• UTC time
• Tray

The default swaybar (the thing that, with the default config, is just a black rectangle at the top indicating workspaces and showing the time).

For me it’s at the bottom and using a script invoking conky as a source to display stuff. And that stuff is:

• Time left till some important timestamp (usually that cute boys bd :3)
• Audio status (muted/disabled or volume) (Because that bastard loves to randomly unmute without me knowing and blasting random shit in class)
• Playerctl status (which is disabled currently, as it took 5 seconds to run when using spotifyd)
• Bluetooth status (either blocked (by rfkill), not connected or the devices connected)
• Wifi status (either blocked (by rfkill), not connected or the IPv6 and then wifi strength, mame and the IPv4)
• Ethernet status (either down or the IPv4)
• Battery status (charging etc., percentage and time left)
• How much space in the FS is free
• loadavg and temperature of CPU
• Formerly i8k data, including fans status, but that’s not a thing anymore on my new Laptop
• memory used and memory easy free
• the current time (%a %F %T)

Nearly everything is colored based on status (interfaces down -> red, up -> green, battery full -> green, load memory usage over 90% -> red etc.)

I use Waybar-hyprland-git.

None. Just workspaces

I use waybar, on left side:

• clock

• pulseaudio (volume and microphone)
• bandwidth usage

center:

• workspace

right:

• RAM
• cpu temperature
• backlight
• keyboard layout
• bluetooth
• battery
• tray
