Can I use this mechanism to store and retrieve credentials and other parameters?
In the extension’s skin include an [Extras] field under which I could have
various parameters. for example:
[Extras]
snowIP=‘192.168.1.###’
snowUser=‘me’
snowPW=‘password’
snowMAXmm=2438
then, in the extension I can grab the parameters using something like:
snowIP=self.skin_dict['Extras'][’snowIP’]
etc
thanks once more!
