Here are the things I would like (or I should) do for the next releases:

* Implement the classic "-d" option for sar (report statistics for each block
  device). It still depends on the data supplied by the kernel anyway.

* Update sysstat to make it work with kernels 2.4.x.

* Add a vmstat command (not sure about this, since it already exists in common
  Linux distributions).

* Get rid of the limit on the number of processors (NR_CPUS).

* Add more statistics to sar and mpstat (and iostat) when available in Linux
  kernels.
  Numerous network activities are already available (see /proc/snmp for
  example), but I am rather reluctant to display them: there are too many of
  them and sar becomes bigger and bigger...

* Implement a "-P" option for sar to display all statistics on a per-processor
  basis.

* Add a plotting program, something like "sagd". But I really lack experience
  in gtk, tcl/tk etc. programming. A volunteer out there ?

* Should clean the code (smaller functions, etc.), perhaps with more modules.
