BTW, I've started the reimplementation of qubes-i3status as a Python wrapper around i3status. I am trying to be quite conservative – in the default settings, there should be no visible difference except CPU load, periodic freezes and bug fixes (battery status).
* Some indicators (battery, load and time) are already present, they just need some adjustments of the format in order to be a drop-in replacement. * Disk status was easy to implement. I just need to verify that it can properly handle the change of default pool. * Running qubes: I need to study the events deeper… * NetVM status – currently, it is disabled and discouraged. I might decide to reimplement this, but I am not 100% sure right now.
