I have been testing btop for 10 days and it works very well and uses less CPU and RAM than bpytop.
In future Mabox releases, btop will replace bpytop.
If you want to make this change now:
Remove bpytop:
yay -Rc bpytop
Install btop:
yay -S btop
Replace it in Openbox rc.xml - so you can still use super + h to run it.
sd -s bpytop btop ~/.config/openbox/rc.xml
Replace it in left sidepanel:
sd -s bpytop btop ~/.config/mabox/places-append.csv
what is sd command?
sd is search and replace cli tool installed by default in Mabox.
