This sounds a good solution, so it can be set under the general options?
However, one would still need to know when to default that as on, and
the config file would differ from one machine to another.
What if the scenario is, the tool is integrated in an application that one
would just need to install it and use it without having the need to
look into the configs?
Please do let me know if I misunderstood what you mean. I would be
glad to try the solution you have mentioned, and if there are other
good idea, please shed more.
