Here's another interesting idea: presenting the list of file in use by a
certain process (see the fuser tool).

And another: network traffic statistics. And if you can implement
per-process bandwidth consumption it would kick iptraff's behind, since
that can only show totals and per IP/interface consumption.

But let's not stop here, let's think at a greater scale. :) How about
making htop into a tool that can be used to show per-process consumption of
network, cpu, memory and disk resources (both disk throughput and files
open)?

I don't know about other people but I've always wished for such a tool. It
would be useful for a lot of things, from finding bottlenecks to
identifying rogue processes and trojans. Imagine, being able to know
everything your processes do using one tool instead of having to hunt and
correlate information from /proc entries and several other tools.

In such an eventuality, the interface could have 3 modes (network,
disk+files, cpu+mem) and the user could switch between them. In all 3 cases
a list of processes could be shown and ENTER on a process could show
additional information. For instance, in disk mode the list could show for
each process the disk throughput and number of open files, while pressing
ENTER would give the list of open files.

Or, the screen for a certain process could offer all the information there
is about it (disk, cpu, mem, net).
