[Qgis-developer] Usability of searches

Hi Paolo,

I wouldn't say it is bad usability that you have to go through the 
attribute table to search for features - because usually you want to see 
the results in the table or form anyway - or you want to do something 
with the filtered or selected features - such as viewing or modifying 
their attributes.

For QGIS 2.16, Nyall will work on the multi-attribute editor and there 
will also be search directly from multiple attributes in the form. So 
there is already work going on for improving search from the form with 
multiple attributes. If you have any input on that, please tell us.ยจ
