[Qgis-developer] No Zoom to selected point

[Marco Hugentobler]

Hi Bernhard

If one point is selected, it is somehow undefined how far to zoom in. 
Earlier behaviour was to just zoom in by a factor of two. This however 
is very unconvenient if you repeatedly select entries in the attribute 
table and click 'zoom to selected'.

Regards,
Marco
