UI: make the width of "Process Name" column automatically fit the available horizontal space
Try this two things:
Open nautilus > set the view mode to "list" > resize the window a few times
=> the "Name" column automatically resizes according to available width.
Open gnome-system-monitor > resize the window a few times
=> not any column automically gets wider or narrower in order to fit the available space.
My suggestion here is to make the "Process Name" column work just like the nautilus "Name" column so to always fill the entire available space.
I see that gnome-system-monitor lets the user decide which column he wants to have, so it might be possible that the "Process Name" is not shown at all. On the other end, it is also true that such column is the maybe the only one whose content might be very wide. So it makes sense to make only that column a bit "special".
What do you think about this?
