to my config, just underneath the SWAP-Info. This displays the string "Charging!" if the battery is being charged (and not just connected to the PC/Power together wit the percentage and a bar. (see screenshot) The information is updated every 30 sec to save CPU-Cycles. The only thing I miss is the option "default_bar_size" which is not available in the current build. With this option the bar would be the right size. Have fun!
