I don't know if it's even possible in linux, but would be great to have this feature: to see how much physical and swap memory every process use.
On Linux, it's in /proc/#/status on the VmSwap line.
A PR for this is definitely welcome!
I'm closing this entry for now since the issues page keeps open bugs only; feature requests are filed in the feature requests label. More info here! Thank you for the feedback!
