You can force a status update by sending a signal 1 (SUGHUP)
to the corresponding process:
kill -s 1 <pid_of_john_instance>
May be you should update the status only if the user presses
a "refresh status info" button.
Another option would be to send the kill -s 1 ... command only
if the user actually is displaying at the status information.
The update interval could be configurable by the user.
This should, however, be a new option, not the Save = ... option
in the [Options] section.
Maybe the [Options] section should be renamed to [Options:General]
or [Options.General], with a fallback to [Options] when it is missing.
GUI specific options could be configured under [Options:GUI] or
[Options.GUI]
[Options.GUI] is probably the better alternative.
If at some time in the future there are different GUIs,
we could use [Options.GUI] for common GUI options,
[Options.GUI:Johnny] for options specific for Johhny,
and so on.
Somewhat OT for GUI implementation problems, but:
One could also argue that options specific to markov mode
justify a separate section.
That means, instead of
[Options]
...
MkvLvl = 200
MkvMaxLen = 12
we could use
[Options.Markov]
MkvLvl = 200
MkvMaxLen = 12
or even
[Options.Markov]
Level = 200
MaxLen = 12
A fallback to the old/current way of specifying these options
in the john.conf [Options] section is probably required.
Even extending this would be possible/reasonable:
[Options.Markov:my_markov_session]
Level = 200
MaxLen = 12
StatsFile = $JOHN/stats
