not zoom out, zoom in sorry

>> a) QGIS points to a fraction (say 1%) of the overall width of all layers

>>
>> b) The user can define a map scale that QGIS should use when zooming to
>> that single point
>>
>> c) a combination of a) and b): if b) is set in the project, use the
>> setting, if not set, use the mechanism of a)
>>
>> What are you thoughts?

>> Thanks,
