Is there a way to make a System Monitor page that would dynamically update the disk stats based on the disks that are connected to the PC?
For example, the page would show the IOps and usage of all the internally connected disk, then update the page if it detects a USB flash drive.
I imagine it’s possible as Plasma already detects when USB drives are connected via (I think udisks) so it would be a matter of hooking System Monitor up to that and listen for changes in disks.
This feature request though should go on https://bugs.kde.org (yes I know it’s called bugs but it tracks feature requests too 
).
